URL: https://github.com/apache/superset/pull/36433#issuecomment-3857331375
## **Sequence Diagram**
The PR removes the deprecated react-hot-loader and its integrations, and
updates the dev build/dev-server to use SWC + React Refresh (Fast Refresh) with
theme merged into preamble and proxy/WebSocket rules so HMR updates are served
correctly. Diagram shows the core developer HMR success path after these
changes.

Developer->>Browser: Edit React component (save)
Browser->>DevServer: HMR websocket connection (watch)
BuildConfig->>DevServer: Configure SWC + React Refresh, remove
react-hot-loader, include theme in preamble, avoid proxying .hot-update and /ws
DevServer->>DevServer: Rebuild + emit hot-update (React Refresh
transform)
DevServer-->>Browser: Send hot-update over WS / serve hot-update file
Browser->>Browser: Apply React Refresh update (component replaced
without full reload)
