Rebuild bundle.js to include StateField and StateEffect exports
The previous commit added StateField/StateEffect to includes.js but
didn't rebuild bundle.js (the esbuild+babel output that dune embeds).
Without this, the __CM__StateField and __CM__StateEffect globals were
undefined at runtime, causing TypeError on page load.
Built with: dune build --profile=with-bundle
