fix: switch compose entrypoint to python module and enable asyncio debug in app.py

- Comment out gunicorn entrypoint in compose.yml and use python -m snek.app instead
- Add asyncio import and create async main() function in app.py
- Enable asyncio event loop debug mode via loop.set_debug(True)
- Replace direct web.run_app call with asyncio.run(main()) for proper async context
