feat(cli): add AI Agent Instructions to --help output

Add dedicated section in help for AI coding assistants with:
- Step-by-step workflow (scan → fix → verify → expand)
- Recommended commands for each step
- Output format description for parsing
- Priority order guidance (CRITICAL → HIGH → MEDIUM → LOW)

This helps AI agents (Claude, Copilot, Cursor) immediately
understand how to use Guardian and take action.
