fix: refine bundle caching and remove dev logging artifacts

- Update static file fetcher in `server.tsx` to apply `public, max-age=31536000, immutable` headers only to minified assets identified by a hash pattern (e.g., `chunk-xxxxxx.js`).
- Apply `no-cache` header explicitly to unhashed files (such as `index.html`) to ensure the latest entrypoint is always served.
- Removed dev artifacts, build output files, and patches from the workspace to clean up the branch.
- Reverted unintentional `React.lazy` changes in `src/App.tsx` as requested.
