Fix Netlify build by restoring dist build script and config

- Restore `scripts/build-dist.mjs` to clean `dist/`, build CSS, and copy assets.
- Update `package.json` to use the new build script and serve `dist`.
- Update `netlify.toml` to publish the `dist` directory.
- Update `dist/` artifacts to match current source.
