chore(regen): update streaming control types

[GregHolmes]

Summary

• Regenerate the Java SDK from deepgram-docs main with fern-java-sdk 4.23.1.
• Retain the intentional direct Topics and Intents segments API introduced in 0.11.0.
• Preserve existing Speak V2 failure-code Visitor implementations with a default CONTROL_COMBINATION_INVALID handler that delegates to visitUnknown.
• Reapply existing transport, WebSocket, union-default, model, header, and fields-less hashCode patches.

Release

• This is a maintenance regeneration. Keep committed Maven, Gradle, Fern metadata, and SDK header versions at the published 0.11.1.
• Release Please owns the next version bump when a user-facing release is needed.

Compatibility

• Preserve repeated query values and additionalProperties on streaming connections.
• Preserve forward-compatible handling of unknown WebSocket frames.
• Preserve legacy versionless Agent listen-provider payloads.
• Preserve the Flux Renee model constant.

Validation

• ./gradlew spotlessCheck test compileExamples
• Fields-less hashCode sweep
• git diff --check

Approving. I pushed c63d88f with text-only fixes; no code behavior changed.

What this PR does: regenerates the Java SDK with Fern 4.23.1, re-applies the manual patches, and keeps the version at 0.11.1. User-visible changes: FLUX_RENEE_EN is deprecated (Renee is an unlisted voice per #project-flux-tts, 2026-08-19, and it still synthesizes), and SpeakV2ConfigureFailureCode.Visitor no longer requires visitControlCombinationInvalid().

What I checked

• Build and tests? Pass: CI, plus spotlessCheck test compileExamples in Docker before and after my commit.
• Patches survived? Yes. All frozen paths are present, no .bak leftovers, the hashCode sweep is clean, and no new voices were dropped.
• Is Renee still live? Yes. POST /v2/speak?model=flux-renee-en returns 200 audio.

What c63d88f fixes

• ClientOptions.close() Javadoc again says sync execute() calls still run after close; only async calls hit the rejected dispatcher.
• The Renee deprecation note now points callers to a listed voice and GET /v2/models.
• AGENTS.md: Renee was delisted on purpose, so drop it at the next major; the SpeakV2ConfigureFailureCode entry gets the .bak workflow.
• README and LiveReconfigure: an over-limit keyterm update does not close the stream. Verified in 2 prod runs (request IDs 01a13abb-0c5f-7b91-a305-2f513d6946a4 and 01a13abc-7911-7e83-98c0-55990aba766b).

Follow-ups (not blocking)

• The deepgram-docs spec still says an over-limit keyterm update stops transcription and closes with 1011, and that text regenerates into ListenV1Configure Javadoc.
• Listen V1 doesn't model ConfigureFailure, so the V1 client reports it to onError as "Update your SDK version". The server sent it in only 1 of 2 identical runs.
• Optional: make Visitor.visitFluxReneeEn() a default that delegates to visitUnknown.
