- AsgiContext and AsgiWebSocket now default missing scope key
to 'http' / 'ws' respectively (Daphne omits it for websocket scopes)
- Add regression test for websocket scope without scheme
- Update example/session.py WS handler to read the session; cookie must
be set via HTTP first because common ASGI servers ignore the headers
field on websocket.accept
- Update README with the same caveat about Granian/Daphne/curl
Replace wrapper-based SessionMiddleware/OIDCApp with KayaMixin subclasses
applied via KayaApp(mixins=[...]). Mixins hook into handle_request and
handle_websocket via before/after hooks, so both ASGI and RSGI keep working.
Mixin dependencies are applied automatically and deduplicated.
