Introduce a ReloadSocketManager and client ReloadService for automatic page reloads when the server restarts. Serve UI assets from an embedded generated file and add Deno tasks to bundle the UI and compile native binaries for multiple platforms. Also update dev watch workflow and ignore generated embedded UI file.
- Add ReloadSocketManager (ts/reload-socket.ts) to broadcast a server instance ID to connected clients for hot-reload.
- Integrate reload socket into StackGalleryRegistry and expose WebSocket upgrade endpoint at /ws/reload.
- Add Angular ReloadService (ui/src/app/core/services/reload.service.ts) to connect to the reload WS and trigger page reloads with exponential reconnect.
- Serve static UI files from an embedded generated module (getEmbeddedFile) and add SPA fallback to index.html.
- Ignore generated embedded UI file (ts/embedded-ui.generated.ts) in .gitignore.
- Add Deno tasks in deno.json: bundle-ui, bundle-ui:watch, compile targets (linux/mac x64/arm64) and a release task to bundle + compile.
- Update package.json watch script to run BACKEND, UI and BUNDLER concurrently (deno task bundle-ui:watch).
