feat: add async logging to temp file with lifecycle management

Implement async logging system that writes to /tmp/codex-wrapper-{pid}.log during execution and auto-deletes on exit.

- Add Logger with buffered channel (cap 100) + single worker goroutine
- Support INFO/DEBUG/ERROR levels
- Graceful shutdown via signal.NotifyContext
- File cleanup on normal/signal exit
- Test coverage: 90.4%

-# Claude Code Plugin System
-
-本项目已支持Claude Code插件系统，可以将命令和代理打包成可安装的插件包。
-
-## 插件配置
-
-插件配置文件位于 `.claude-plugin/marketplace.json`，定义了所有可用的插件包。
-
-## 可用插件
-
-### 1. Requirements-Driven Development
-- **描述**: 需求驱动的开发工作流，包含90%质量门控
-- **命令**: `/requirements-pilot`
-- **代理**: requirements-generate, requirements-code, requirements-testing, requirements-review
-
-### 2. BMAD Agile Workflow
-- **描述**: 完整的BMAD敏捷工作流（产品负责人→架构师→SM→开发→QA）
-- **命令**: `/bmad-pilot`
-- **代理**: bmad-po, bmad-architect, bmad-sm, bmad-dev, bmad-qa, bmad-orchestrator
-
-### 3. Development Essentials
-- **描述**: 核心开发命令套件
-- **命令**: `/code`, `/debug`, `/test`, `/optimize`, `/review`, `/bugfix`, `/refactor`, `/docs`, `/ask`, `/think`
-- **代理**: code, bugfix, bugfix-verify, code-optimize, debug, develop
-
-### 4. Advanced AI Agents
-- **描述**: 高级AI代理，集成GPT-5进行深度分析
-- **代理**: gpt5
-
-## 使用插件命令
-
-### 列出所有可用插件
-```bash
-/plugin list
-```
-
-### 查看插件详情
-```bash
-/plugin info <plugin-name>
-```
-例如：`/plugin info requirements-driven-development`
-
-### 安装插件
-```bash
-/plugin install <plugin-name>
-```
-例如：`/plugin install bmad-agile-workflow`
-
-### 移除插件
-```bash
-/plugin remove <plugin-name>
-```
-
-## 创建自定义插件
-
-要创建自己的插件：
-
-1. 在 `.claude-plugin/marketplace.json` 中添加新的插件定义
-2. 指定插件包含的命令和代理文件路径
-3. 设置适当的元数据（版本、作者、关键词等）
-
-示例插件结构：
-```json
-{
-  "name": "my-custom-plugin",
-  "source": "./",
-  "description": "自定义插件描述",
-  "version": "1.0.0",
-  "commands": [
-    "./commands/my-command.md"
-  ],
-  "agents": [
-    "./agents/my-agent.md"
-  ]
-}
-```
-
-## 分享插件
-
-要分享插件给其他项目：
-1. 复制整个 `.claude-plugin` 目录到目标项目
-2. 确保相关的命令和代理文件存在
-3. 在新项目中使用 `/plugin` 命令管理插件
-
-## 注意事项
-
-- 插件系统遵循Claude Code的插件规范
-- 所有命令和代理文件必须是有效的Markdown格式
-- 插件配置支持版本管理和依赖关系
-- 插件可以包含多个命令、代理和输出样式
-

 ## Notes
 
-- **Recommended**: Use `uv run` for automatic Python environment management (requires uv installed)
-- **Alternative**: Direct execution `./codex.py` (uses system Python via shebang)
-- Python implementation using standard library (zero dependencies)
-- All automated runs must use the Bash tool with the fixed timeout to provide dual timeout protection and unified logging/exit semantics; any alternative approach is limited to manual foreground execution.
-- Cross-platform compatible (Windows/macOS/Linux)
-- PEP 723 compliant (inline script metadata)
-- Runs with `--dangerously-bypass-approvals-and-sandbox` for automation (new sessions only)
+- **Binary distribution**: Single Go binary, zero dependencies
+- **Installation**: Download from GitHub Releases or use install.sh
+- **Cross-platform compatible**: Linux (amd64/arm64), macOS (amd64/arm64)
+- All automated runs must use the Bash tool with the fixed timeout to provide dual timeout protection and unified logging/exit semantics
