feat: add auto-update checker and GitHub Actions release

Features:
- SessionStart hook checks for plugin updates via GitHub Releases API
- Fallback to git commit SHA comparison when no releases exist
- Subtle promotional footer in update notifications
- Stop hook shows task completion with optional promo (30% chance)
- Fallback to systemMessage when macOS notifications unavailable

Improvements:
- Clean up privacy-sensitive content (paths, branch names)
- Simplify MONITOR_README.md documentation
- Add Support & Community section to README
- Add GitHub Actions workflow for automatic releases

Hooks:
- on-session-start.py: Update checker with GitHub Releases API
- on-stop.py: Task completion notification with fallback
