feat(skills): add CCW orchestrator and refactor command-guide to ccw-help

CCW Skill (new):
- Stateless workflow orchestrator with intent classification
- 6 workflow combinations: rapid, full, coupled, bugfix, issue, ui
- External configuration: intent-rules.json, workflow-chains.json
- Implicit CLI tool injection (Gemini/Qwen/Codex)
- TODO tracking integration for workflow progress

CCW-Help Skill (refactored from command-guide):
- Renamed command-guide → ccw-help
- Removed reference folder duplication
- Source paths now relative from index/ (../../../commands/...)
- Added all-agents.json index
- Simplified SKILL.md following CCW pattern
