Remove duplicate frontend assets from wheel to reduce package size (#4567)

The wheel currently ships frontend/public/, frontend/src/, and
frontend/*.lock alongside frontend/dist/. These are build-time inputs
that Vite already copies into dist/ during the build step:

- public/ is copied verbatim into dist/ by vite build (28.6 MB duplicate)
- src/ is TSX source compiled into dist/assets/*.js (2.1 MB, not used at runtime)
- *.lock files are package manager lockfiles (0.9 MB, not used at runtime)

The backend only serves from frontend/dist/ (see main.py setup_frontend
and run.py frontend_path). Nothing references public/ or src/ at runtime.

This drops the wheel from ~62.7 MB to ~31 MB.
