Add NPM distribution support with hybrid installation approach

Major changes:
- Add package.json with NPM packaging configuration
- Create Node.js CLI interface (bin/claude-hooks.js) with full command set
- Convert bash scripts to Python for better npm integration
- Add npm postinstall/preuninstall hooks for automatic setup
- Update bootstrap prompt to recommend NPM method with git fallback
- Enhance README with NPM-first documentation
- Maintain backward compatibility with existing git installation

Features:
- npm install -g claude-hooks for easy distribution
- claude-hooks init/status/test/backup/uninstall commands
- Automatic Python dependency installation
- Conflict detection and prevention
- Hybrid approach supporting both npm and git workflows

This resolves installation complexity while maintaining developer flexibility.
