Features

• feat(runtime-websocket): negotiate session capabilities (2110718)

  Send websocket client capabilities and session metadata during the handshake and let the runtime respond with the negotiated settings.

  Use negotiated session ids consistently across websocket logging, metrics, events and tracker state, while keeping legacy runtimes compatible through the existing compression query parameter fallback.

  Also reject custom AbstractWebsocketClient subclasses annotated with @​ClientEndpoint so unsupported extension patterns fail fast with a clear error message.

Bug Fixes

• fix(test): isolate shared fixture interceptor state (e774b24)
• fix(test): ignore unreachable consumers in fixture waits (3b3336c)
