Bump to v0.1.1 — add README to npm package, fix release workflow

- Copy README.md to npm/ so it appears on npmjs.com
- Bump version to 0.1.1 in both pyproject.toml and npm/package.json
- Update release workflow to auto-copy README before npm publish
- Add .npmignore to exclude .venv and node_modules
