feat: bundle skill assets in npm package (#12)

- Add assets folder with all skill files (.claude, .cursor, .windsurf, .agent, .shared)
- Simplify init command to copy from bundled assets instead of GitHub download
- Remove --version option (version tied to npm package)
- No more GitHub API rate limits
- Works offline
- Bump to v1.1.0
