refactor(cli): remove --agent flag and enhance agent execution context

- Remove --agent parameter from all CLI commands (now default behavior)
- Restore and enhance Task() invocation context for cli-execution-agent
- Add detailed execution phases and context discovery strategies
- Simplify documentation by removing redundant CLI command templates
- Consolidate output documentation to unified format

Modified commands:
- /cli:analyze, /cli:chat, /cli:execute
- /cli:mode:plan, /cli:mode:code-analysis, /cli:mode:bug-diagnosis

-- `--agent` - Use cli-execution-agent for automated context discovery
 - `--enhance` - Enhance task with `/enhance-prompt`

 ## Execution Flow
 
-### Standard Mode
-1. Parse tool selection (default: gemini)
-2. Optional: enhance with `/enhance-prompt`
-3. Detect directory from `--cd` or auto-infer
-4. Build command with template
-5. Execute planning (read-only, no code generation)
-6. Save to `.workflow/WFS-[id]/.chat/`

-Delegates to agent for intelligent planning:

   prompt=`
     Task: ${planning_task}

-    Agent responsibilities:
+    Execute strategic architecture planning:
+
     1. Context Discovery:
-       - Analyze current architecture
-       - Identify affected components
-       - Map dependencies and impacts
+       - Analyze current architecture structure
+       - Identify affected components and modules
+       - Map dependencies and integration points
+       - Assess modification impacts (scope, complexity, risks)
 
-    2. CLI Command Generation:
-       - Build Gemini/Qwen/Codex command
-       - Include architecture context
-       - Apply ~/.claude/workflows/cli-templates/prompts/planning/01-plan-architecture-design.txt template
+    2. Planning Analysis:
+       - Apply strategic planning template
+       - Generate modification plan with phases
+       - Document architectural decisions and rationale
+       - Identify potential conflicts and mitigation strategies
 
-    3. Execution & Output:
-       - Execute strategic planning
-       - Generate modification plan
-       - Save to .workflow/.chat/
+    3. CLI Command Construction:
+       - Tool: ${tool_flag || 'gemini'} (qwen fallback, codex for implementation guidance)
+       - Directory: cd ${cd_path || '.'} &&
+       - Context: @**/* (full architecture context)
+       - Mode: analysis (read-only, no code generation)
+       - Template: planning/01-plan-architecture-design.txt
+
+    4. Output Generation:
+       - Strategic modification plan
+       - Impact analysis and risk assessment
+       - Implementation roadmap
+       - Save to .workflow/WFS-[id]/.chat/plan-[timestamp].md (or .scratchpad/)

 ## Core Rules
 
-- **Planning only**: Creates modification plans, does NOT generate code
-- **Template**: Uses `~/.claude/workflows/cli-templates/prompts/planning/01-plan-architecture-design.txt` for strategic planning
-- **Output**: Saves to `.workflow/WFS-[id]/.chat/`

-## CLI Command Templates
-
-**Gemini/Qwen** (default, planning only):
-```bash
-cd [dir] && gemini -p "
-PURPOSE: [goal]
-TASK: Architecture planning
-MODE: analysis
-CONTEXT: @**/*
-EXPECTED: Modification plan, impact analysis
-RULES: $(cat ~/.claude/workflows/cli-templates/prompts/planning/01-plan-architecture-design.txt)
-"
-# Qwen: Replace 'gemini' with 'qwen'
-```
-
-**Codex** (planning + implementation guidance):
-```bash
-codex -C [dir] --full-auto exec "
-PURPOSE: [goal]
-TASK: Architecture planning
-MODE: analysis
-CONTEXT: @**/*
-EXPECTED: Plan, implementation roadmap
-RULES: $(cat ~/.claude/workflows/cli-templates/prompts/planning/01-plan-architecture-design.txt)
-" -m gpt-5 --skip-git-repo-check -s danger-full-access
-```

-- **No session**: `.workflow/.scratchpad/plan-[desc]-[timestamp].md`
