feat: add requirements for claude-commands hooks feature

Created simple specification for hooks installation:
- REQ-HOOKS-001: List available hooks (--list)
- REQ-HOOKS-002: Install hooks (--install)
- REQ-HOOKS-003: Show help (--help)
- REQ-HOOKS-004: Handle missing settings.json

Implementation approach:
- Copy hook scripts from hooks/ to ~/.claude/hooks/
- Update settings.json to configure hooks
- Backup existing settings before changes
- Make hooks executable with chmod +x

Simple file operations for security hook deployment.
