fix: parser critical bugs and add PR #86 compatibility

Fixes 3 critical bugs in parser.go:

1. Gemini detection: Change Delta from bool to *bool for proper field
   presence detection. Fixes issue where delta:false events were lost.

2. Codex detection: Tighten logic to only classify as Codex if
   thread_id exists OR item.type is non-empty. Prevents Claude events
   with item:null/item:{} from being misclassified and dropped.

3. Performance: Move itemHeader parsing inside item.completed case,
   only parse when actually needed.

Additional changes:
- Implement PR #86's Gemini notifyMessage trigger on Status field
  instead of Content, resolving parser.go conflict between PRs
- Add regression tests for all fixed scenarios
- All tests pass: go test ./...

-## Version Requirements
-
-### Codex CLI
-**Minimum version:** Check compatibility with your installation
-
-The codeagent-wrapper uses these Codex CLI features:
-- `codex e` - Execute commands (shorthand for `codex exec`)
-- `--skip-git-repo-check` - Skip git repository validation
-- `--json` - JSON stream output format
-- `-C <workdir>` - Set working directory
-- `resume <session_id>` - Resume previous sessions
-
-**Verify Codex CLI is installed:**
-```bash
-which codex
-codex --version
-```
-
-### Claude CLI
-**Minimum version:** Check compatibility with your installation
-
-Required features:
-- `--output-format stream-json` - Streaming JSON output format
-- `--setting-sources` - Control setting sources (prevents infinite recursion)
-- `--dangerously-skip-permissions` - Skip permission prompts (use with caution)
-- `-p` - Prompt input flag
-- `-r <session_id>` - Resume sessions
-
-**Security Note:** The wrapper only adds `--dangerously-skip-permissions` for Claude when explicitly enabled (e.g. `--skip-permissions` / `CODEAGENT_SKIP_PERMISSIONS=true`). Keep it disabled unless you understand the risk.
-
-**Verify Claude CLI is installed:**
-```bash
-which claude
-claude --version
-```
-
-### Gemini CLI
-**Minimum version:** Check compatibility with your installation
-
-Required features:
-- `-o stream-json` - JSON stream output format
-- `-y` - Auto-approve prompts (non-interactive mode)
-- `-r <session_id>` - Resume sessions
-- `-p` - Prompt input flag
-
-**Verify Gemini CLI is installed:**
-```bash
-which gemini
-gemini --version
-```

-
-By default, myclaude installs to `~/.claude`. You can customize this using the `INSTALL_DIR` environment variable:
-
-```bash
-# Install to custom directory
-INSTALL_DIR=/opt/myclaude bash install.sh
-
-# Update your PATH accordingly
-export PATH="/opt/myclaude/bin:$PATH"

-- `$INSTALL_DIR/bin/` - codeagent-wrapper binary
-- `$INSTALL_DIR/skills/` - Skill definitions
-- `$INSTALL_DIR/config.json` - Configuration file
-- `$INSTALL_DIR/commands/` - Slash command definitions
-- `$INSTALL_DIR/agents/` - Agent definitions
-
-**Note:** When using a custom installation directory, ensure that `$INSTALL_DIR/bin` is added to your `PATH` environment variable.

-## FAQ (Frequently Asked Questions)
-
-### Q1: `codeagent-wrapper` execution fails with "Unknown event format"
-
-**Problem:**
-```
-Unknown event format: {"type":"turn.started"}
-Unknown event format: {"type":"assistant", ...}
-```
-
-**Solution:**
-This is a logging event format display issue and does not affect actual functionality. It will be fixed in the next version. You can ignore these log outputs.
-
-**Related Issue:** [#96](https://github.com/cexll/myclaude/issues/96)
-
----
-
-### Q2: Gemini cannot read files ignored by `.gitignore`
-
-**Problem:**
-When using `codeagent-wrapper --backend gemini`, files in directories like `.claude/` that are ignored by `.gitignore` cannot be read.
-
-**Solution:**
-- **Option 1:** Remove `.claude/` from your `.gitignore` file
-- **Option 2:** Ensure files that need to be read are not in `.gitignore` list
-
-**Related Issue:** [#75](https://github.com/cexll/myclaude/issues/75)
-
----
-
-### Q3: `/dev` command parallel execution is very slow
-
-**Problem:**
-Using `/dev` command for simple features takes too long (over 30 minutes) with no visibility into task progress.
-
-**Solution:**
-1. **Check logs:** Review `C:\Users\User\AppData\Local\Temp\codeagent-wrapper-*.log` to identify bottlenecks
-2. **Adjust backend:**
-   - Try faster models like `gpt-5.1-codex-max`
-   - Running in WSL may be significantly faster
-3. **Workspace:** Use a single repository instead of monorepo with multiple sub-projects
-
-**Related Issue:** [#77](https://github.com/cexll/myclaude/issues/77)
-
----
-
-### Q4: Codex permission denied with new Go version
-
-**Problem:**
-After upgrading to the new Go-based Codex implementation, execution fails with permission denied errors.
-
-**Solution:**
-Add the following configuration to `~/.codex/config.yaml` (Windows: `c:\user\.codex\config.toml`):
-```yaml
-model = "gpt-5.1-codex-max"
-model_reasoning_effort = "high"
-model_reasoning_summary = "detailed"
-approval_policy = "never"
-sandbox_mode = "workspace-write"
-disable_response_storage = true
-network_access = true
-```
-
-**Key settings:**
-- `approval_policy = "never"` - Remove approval restrictions
-- `sandbox_mode = "workspace-write"` - Allow workspace write access
-- `network_access = true` - Enable network access
-
-**Related Issue:** [#31](https://github.com/cexll/myclaude/issues/31)
-
----
-
-### Q5: Permission denied or sandbox restrictions during execution
-
-**Problem:**
-Execution fails with permission errors or sandbox restrictions when running codeagent-wrapper.
-
-**Solution:**
-Set the following environment variables:
-```bash
-export CODEX_BYPASS_SANDBOX=true
-export CODEAGENT_SKIP_PERMISSIONS=true
-```
-
-Or add them to your shell profile (`~/.zshrc` or `~/.bashrc`):
-```bash
-echo 'export CODEX_BYPASS_SANDBOX=true' >> ~/.zshrc
-echo 'export CODEAGENT_SKIP_PERMISSIONS=true' >> ~/.zshrc
-```
-
-**Note:** These settings bypass security restrictions. Use with caution in trusted environments only.

-
-### 0. Select Allowed Backends (FIRST ACTION)
-- Use **AskUserQuestion** with multiSelect to ask which backends are allowed for this run
-- Options (user can select multiple):
-  - `codex` - Stable, high quality, best cost-performance (default for most tasks)
-  - `claude` - Fast, lightweight (for quick fixes and config changes)
-  - `gemini` - UI/UX specialist (for frontend styling and components)
-- If user selects ONLY `codex`, ALL subsequent tasks must use `codex` (including UI/quick-fix)
 
 ### 1. Clarify Requirements
 - Use **AskUserQuestion** to ask the user directly
 - No scoring system, no complex logic
 - 2–3 rounds of Q&A until the requirement is clear
 
-### 2. codeagent Analysis + Task Typing + UI Detection
+### 2. codeagent Analysis & UI Detection
 - Call codeagent to analyze the request in plan mode style
 - Extract: core functions, technical points, task list (2–5 items)
-- For each task, assign exactly one type: `default` / `ui` / `quick-fix`
 - UI auto-detection: needs UI work when task involves style assets (.css, .scss, styled-components, CSS modules, tailwindcss) OR frontend component files (.tsx, .jsx, .vue); output yes/no plus evidence
 
 ### 3. Generate Dev Doc
 - Call the **dev-plan-generator** agent
 - Produce a single `dev-plan.md`
 - Append a dedicated UI task when Step 2 marks `needs_ui: true`
-- Include: task breakdown, `type`, file scope, dependencies, test commands
+- Include: task breakdown, file scope, dependencies, test commands
 
 ### 4. Concurrent Development
 - Work from the task list in dev-plan.md
-- Route backend per task type (with user constraints + fallback):
+- Use codeagent per task with explicit backend selection:
-  - `default` → `codex`
+  - Backend/API/DB tasks → `--backend codex` (default)
-  - `ui` → `gemini` (enforced when allowed)
+  - UI/style/component tasks → `--backend gemini` (enforced)
-  - `quick-fix` → `claude`
-  - Missing `type` → treat as `default`
-  - If the preferred backend is not allowed, fallback to an allowed backend by priority: `codex` → `claude` → `gemini`
 - Independent tasks → run in parallel
 - Conflicting tasks → run serially

+- **Flow impact**: Step 2 auto-detects UI work; Step 3 appends a separate UI task in `dev-plan.md` when detected

-
-1. **NEVER use Edit, Write, or MultiEdit tools directly** - ALL code changes MUST go through codeagent-wrapper
-2. **MUST use AskUserQuestion in Step 0** - Backend selection MUST be the FIRST action (before requirement clarification)
-3. **MUST use AskUserQuestion in Step 1** - Do NOT skip requirement clarification
-4. **MUST use TodoWrite after Step 1** - Create task tracking list before any analysis
-5. **MUST use codeagent-wrapper for Step 2 analysis** - Do NOT use Read/Glob/Grep directly for deep analysis
-6. **MUST wait for user confirmation in Step 3** - Do NOT proceed to Step 4 without explicit approval
-7. **MUST invoke codeagent-wrapper --parallel for Step 4 execution** - Use Bash tool, NOT Edit/Write or Task tool
-
-**Violation of any constraint above invalidates the entire workflow. Stop and restart if violated.**

+  - Use AskUserQuestion to clarify requirements directly
-  - Ask which backends are allowed for this /dev run
-  - Options (user can select multiple):
-    - `codex` - Stable, high quality, best cost-performance (default for most tasks)
-    - `claude` - Fast, lightweight (for quick fixes and config changes)
-    - `gemini` - UI/UX specialist (for frontend styling and components)
-  - Store the selected backends as `allowed_backends` set for routing in Step 4
-  - Special rule: if user selects ONLY `codex`, then ALL subsequent tasks (including UI/quick-fix) MUST use `codex` (no exceptions)
-
-- **Step 1: Requirement Clarification [MANDATORY - DO NOT SKIP]**
-  - MUST use AskUserQuestion tool
   - Focus questions on functional boundaries, inputs/outputs, constraints, testing, and required unit-test coverage levels
   - Iterate 2-3 rounds until clear; rely on judgment; keep questions concise
-  - After clarification complete: MUST use TodoWrite to create task tracking list with workflow steps
 
-- **Step 2: codeagent-wrapper Deep Analysis (Plan Mode Style) [USE CODEAGENT-WRAPPER ONLY]**
+- **Step 2: codeagent Deep Analysis (Plan Mode Style)**
 
-  MUST use Bash tool to invoke `codeagent-wrapper` for deep analysis. Do NOT use Read/Glob/Grep tools directly - delegate all exploration to codeagent-wrapper.
+  Use codeagent Skill to perform deep analysis. codeagent should operate in "plan mode" style and must include UI detection:
-
-  **How to invoke for analysis**:
-  ```bash
-  # analysis_backend selection:
-  # - prefer codex if it is in allowed_backends
-  # - otherwise pick the first backend in allowed_backends
-  codeagent-wrapper --backend {analysis_backend} - <<'EOF'
-  Analyze the codebase for implementing [feature name].

-  - NEVER use Edit, Write, MultiEdit, or Task tools to modify code directly
-  - Backend routing (must be deterministic and enforceable):
-    - Task field: `type: default|ui|quick-fix` (missing → treat as `default`)
-    - Preferred backend by type:
-      - `default` → `codex`
-      - `ui` → `gemini` (enforced when allowed)
-      - `quick-fix` → `claude`
-    - If user selected `仅 codex`: all tasks MUST use `codex`
-    - Otherwise, if preferred backend is not in `allowed_backends`, fallback to the first available backend by priority: `codex` → `claude` → `gemini`
-  - Build ONE `--parallel` config that includes all tasks in `dev-plan.md` and submit it once via Bash tool:

-description: Install Claude skills from GitHub repositories with automated security scanning. Triggers when users want to install skills from a GitHub URL, need to browse available skills in a repository, or want to safely add new skills to their Claude environment.
----
-
-# Skill Install
-
-## Overview
-
-Install Claude skills from GitHub repositories with built-in security scanning to protect against malicious code, backdoors, and vulnerabilities.
-
-## When to Use
-
-Trigger this skill when the user:
-- Provides a GitHub repository URL and wants to install skills
-- Asks to "install skills from GitHub"
-- Wants to browse and select skills from a repository
-- Needs to add new skills to their Claude environment
-
-## Workflow
-
-### Step 1: Parse GitHub URL
-
-Accept a GitHub repository URL from the user. The URL should point to a repository containing a `skills/` directory.
-
-Supported URL formats:
-- `https://github.com/user/repo`
-- `https://github.com/user/repo/tree/main/skills`
-- `https://github.com/user/repo/tree/branch-name/skills`
-
-Extract:
-- Repository owner
-- Repository name
-- Branch (default to `main` if not specified)
-
-### Step 2: Fetch Skills List
-
-Use the WebFetch tool to retrieve the skills directory listing from GitHub.
-
-GitHub API endpoint pattern:
-```
-https://api.github.com/repos/{owner}/{repo}/contents/skills?ref={branch}
-```
-
-Parse the response to extract:
-- Skill directory names
-- Each skill should be a subdirectory containing a SKILL.md file
-
-### Step 3: Present Skills to User
-
-Use the AskUserQuestion tool to let the user select which skills to install.
-
-Set `multiSelect: true` to allow multiple selections.
-
-Present each skill with:
-- Skill name (directory name)
-- Brief description (if available from SKILL.md frontmatter)
-
-### Step 4: Fetch Skill Content
-
-For each selected skill, fetch all files in the skill directory:
-
-1. Get the file tree for the skill directory
-2. Download all files (SKILL.md, scripts/, references/, assets/)
-3. Store the complete skill content for security analysis
-
-Use WebFetch with GitHub API:
-```
-https://api.github.com/repos/{owner}/{repo}/contents/skills/{skill_name}?ref={branch}
-```
-
-For each file, fetch the raw content:
-```
-https://raw.githubusercontent.com/{owner}/{repo}/{branch}/skills/{skill_name}/{file_path}
-```
-
-### Step 5: Security Scan
-
-**CRITICAL:** Before installation, perform a thorough security analysis of each skill.
-
-Read the security scan prompt template from `references/security_scan_prompt.md` and apply it to analyze the skill content.
-
-Examine for:
-1. **Malicious Command Execution** - eval, exec, subprocess with shell=True
-2. **Backdoor Detection** - obfuscated code, suspicious network requests
-3. **Credential Theft** - accessing ~/.ssh, ~/.aws, environment variables
-4. **Unauthorized Network Access** - external requests to suspicious domains
-5. **File System Abuse** - destructive operations, unauthorized writes
-6. **Privilege Escalation** - sudo attempts, system modifications
-7. **Supply Chain Attacks** - suspicious package installations
-
-Output the security analysis with:
-- Security Status: SAFE / WARNING / DANGEROUS
-- Risk Level: LOW / MEDIUM / HIGH / CRITICAL
-- Detailed findings with file locations and severity
-- Recommendation: APPROVE / APPROVE_WITH_WARNINGS / REJECT
-
-### Step 6: User Decision
-
-Based on the security scan results:
-
-**If SAFE (APPROVE):**
-- Proceed directly to installation
-
-**If WARNING (APPROVE_WITH_WARNINGS):**
-- Display the security warnings to the user
-- Use AskUserQuestion to confirm: "Security warnings detected. Do you want to proceed with installation?"
-- Options: "Yes, install anyway" / "No, skip this skill"
-
-**If DANGEROUS (REJECT):**
-- Display the critical security issues
-- Refuse to install
-- Explain why the skill is dangerous
-- Do NOT provide an option to override for CRITICAL severity issues
-
-### Step 7: Install Skills
-
-For approved skills, install to `~/.claude/skills/`:
-
-1. Create the skill directory: `~/.claude/skills/{skill_name}/`
-2. Write all skill files maintaining the directory structure
-3. Ensure proper file permissions (executable for scripts)
-4. Verify SKILL.md exists and has valid frontmatter
-
-Use the Write tool to create files.
-
-### Step 8: Confirmation
-
-After installation, provide a summary:
-- List of successfully installed skills
-- List of skipped skills (if any) with reasons
-- Location: `~/.claude/skills/`
-- Next steps: "The skills are now available. Restart Claude or use them directly."
-
-## Example Usage
-
-**User:** "Install skills from https://github.com/example/claude-skills"
-
-**Assistant:**
-1. Fetches skills list from the repository
-2. Presents available skills: "skill-a", "skill-b", "skill-c"
-3. User selects "skill-a" and "skill-b"
-4. Performs security scan on each skill
-5. skill-a: SAFE - proceeds to install
-6. skill-b: WARNING (makes HTTP request) - asks user for confirmation
-7. Installs approved skills to ~/.claude/skills/
-8. Confirms: "Successfully installed: skill-a, skill-b"
-
-## Security Notes
-
-- **Never skip security scanning** - Always analyze skills before installation
-- **Be conservative** - When in doubt, flag as WARNING and let user decide
-- **Critical issues are blocking** - CRITICAL severity findings cannot be overridden
-- **Transparency** - Always show users what was found during security scans
-- **Sandboxing** - Remind users that skills run with Claude's permissions

-# Security Scan Prompt for Skills
-
-Use this prompt template to analyze skill content for security vulnerabilities before installation.
-
-## Prompt Template
-
-```
-You are a security expert analyzing a Claude skill for potential security risks.
-
-Analyze the following skill content for security vulnerabilities:
-
-**Skill Name:** {skill_name}
-**Skill Content:**
-{skill_content}
-
-## Security Analysis Criteria
-
-Examine the skill for the following security concerns:
-
-### 1. Malicious Command Execution
-- Detect `eval()`, `exec()`, `subprocess` with `shell=True`
-- Identify arbitrary code execution patterns
-- Check for command injection vulnerabilities
-
-### 2. Backdoor Detection
-- Look for obfuscated code (base64, hex encoding)
-- Identify suspicious network requests to unknown domains
-- Detect file hash patterns matching known malware
-- Check for hidden data exfiltration mechanisms
-
-### 3. Credential Theft
-- Detect attempts to access environment variables containing secrets
-- Identify file operations on sensitive paths (~/.ssh, ~/.aws, ~/.netrc)
-- Check for credential harvesting patterns
-- Look for keylogging or clipboard monitoring
-
-### 4. Unauthorized Network Access
-- Identify external network requests
-- Check for connections to suspicious domains (pastebin, ngrok, bit.ly, etc.)
-- Detect data exfiltration via HTTP/HTTPS
-- Look for reverse shell patterns
-
-### 5. File System Abuse
-- Detect destructive file operations (rm -rf, shutil.rmtree)
-- Identify unauthorized file writes to system directories
-- Check for file permission modifications
-- Look for attempts to modify critical system files
-
-### 6. Privilege Escalation
-- Detect sudo or privilege escalation attempts
-- Identify attempts to modify system configurations
-- Check for container escape patterns
-
-### 7. Supply Chain Attacks
-- Identify suspicious package installations
-- Detect dynamic imports from untrusted sources
-- Check for dependency confusion attacks
-
