Add comprehensive tests for CLI functionality and CodexLens compatibility

- Introduced tests for stale running fallback in CLI watch functionality to ensure proper handling of saved conversations.
- Added compatibility tests for CodexLens CLI to verify index initialization despite compatibility conflicts.
- Implemented tests for Smart Search MCP usage to validate default settings and path handling.
- Created tests for UV Manager to ensure Python preference handling works as expected.
- Added a detailed guide for CCW/Codex commands and skills, covering core commands, execution modes, and templates.
