chore: re-apply manual patches after regen

- ClientOptions.java: restore deepgram-java-sdk header constants + x-release-please-version markers (gen reverted to wrong SDK name and hardcoded 0.5.1)
- ReconnectingWebSocketListener.java: re-apply maxRetries(0) semantics, configurable connectionTimeoutMs, and applyOptionsOverride() hook
- .fernignore: restore both original paths (still frozen for next cycle)
- examples/listen/LiveStreamingV2.java: drop deleted ListenV2CloseStreamType; ListenV2CloseStream no longer takes a type
- remove transient .bak files
