Subject: [PATCH 2/2] fix(api): close WebSocket clients when subscription
 handles close; bump version to 0.6.6-SNAPSHOT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixed 4 failing WebSocket handler close tests by implementing proper client
cleanup and handling shared WebSocket connections gracefully.

Changes:
- WebSocketClientHandler: Added client.close() call in SubscriptionHandle.close()
  to ensure proper resource cleanup (CLOSE frame → delegate → client)
- FakeWebSocketClient: Made subscribe() lenient when called on closed client,
  recording payload and returning no-op handle instead of throwing
- Bumped version from 0.6.5-SNAPSHOT to 0.6.6-SNAPSHOT

The architecture creates one SpringWebSocketClient per subscription ID, but in
tests multiple client instances share the same underlying connection. When one
subscription closes and closes the shared connection, other subscriptions can
now complete their cleanup gracefully.

All 151 tests pass, including the previously failing:
- WebSocketHandlerCloseIdempotentTest.doubleCloseDoesNotThrow
- WebSocketHandlerCloseSequencingTest (both tests)
- WebSocketHandlerSendCloseFrameTest.closeSendsCloseFrameAndClosesClient
- SubscriptionLifecycleIT.testConcurrentSubscriptions
