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

-    2. CLI Command Generation:
-       - Build Gemini/Qwen/Codex command
-       - Apply analysis template
-       - Include discovered files

+       - Auto-select analysis template based on keywords

 - **Read-only**: Analyzes code, does NOT modify files
-- **Auto-pattern**: Detects file patterns from keywords
-- **Template-based**: Auto-selects analysis template
-- **Output**: Saves to `.workflow/WFS-[id]/.chat/` or `.scratchpad/`

-## File Pattern Auto-Detection
-
-Keywords → file patterns:
-- "auth" → `@**/*auth* @**/*user*`
