Subject: [PATCH] feat(37-01): add COOP/COEP headers to Express server for
 SharedArrayBuffer support

- Add Cross-Origin-Opener-Policy: same-origin middleware before all routes
- Add Cross-Origin-Embedder-Policy: require-corp middleware before all routes
- Required for @ricky0123/vad-react (VAD uses SharedArrayBuffer internally)
