feat: enhance tool triggers and reorder documentation

- Add comprehensive triggers for chat tool including 'ask gemini', 'brainstorm', 'second opinion'
- Enhance triggers for all tools with more natural phrases:
  - think_deeper: added 'deeper analysis', 'critical thinking'
  - review_code: added 'review my code', 'find security issues'
  - debug_issue: added 'stack trace', 'crashed', 'what's wrong'
  - analyze: added 'what does this do', 'how does this work'
  - review_pending_changes: added 'review diff', 'validate implementation'
- Reorder Quick Tool Selection Guide to list chat first
- All tests pass (65 tests), ruff clean, black formatted
