- Add explicit do_handshake() in base_async.py before ALPN check
when do_handshake_on_connect is False
- Mark eventlet worker as deprecated (removal in 26.0)
- Add HTTP/2 gevent example with Docker and tests
- Update documentation to reflect eventlet deprecation
- Remove eventlet websocket example (gevent version exists)
The ALPN fix ensures HTTP/2 works correctly with gevent and eventlet
workers when do_handshake_on_connect config is False (the default).
Without explicit handshake, selected_alpn_protocol() returns None.
