Fix 'stream is not readable' error in SSE message handler

- Replace getRawBody with direct req.body usage since express.json() middleware already parses it
- Add debugging support with --inspect flag for dev scripts
- Add VS Code launch configurations for debugging

The issue was that getRawBody tried to read an already-consumed stream. Since express.json()
middleware is applied globally, we can directly use req.body instead.
