Prompt hooks are unreliable - Claude ignores instructions and generates
verbose analysis despite explicit FORBIDDEN rules. Command hooks guarantee
the exact output we want.
- Add notify.sh script that only outputs for config file changes
- Change hooks.json from prompt type to command type
- Script exits silently for non-config files (no blocking)
Fixes#110
