feat!: (regen) diarization v2 batch GA, listen-provider dedup, think/models route fix (#57)

## Summary

Fern SDK regeneration for 2026-05-14.

### Patches re-applied

- **`ClientOptions.java`** — restored SDK identity headers
(`User-Agent`, `X-Fern-SDK-Name`, `X-Fern-SDK-Version`) to the
`com.deepgram:deepgram-java-sdk` values and re-added `//
x-release-please-version` markers. Generator still overwrites these.
- **`ReconnectingWebSocketListener.java`** — re-applied the three fixes
from #45:
1. `maxRetries(0)` semantics: `retryCount > maxRetries` (initial attempt
always proceeds; cap applies to retries only).
2. Configurable `connectionTimeoutMs` on `ReconnectOptions` (default
4000ms; was hardcoded).
3. `applyOptionsOverride(...)` runtime hook used by
`TransportWebSocketFactory` to apply per-transport reconnect policy
without editing generated WS clients.

No patches were dropped — the generator has not caught up on any of the
above. Both files remain in `.fernignore` at their original paths.

### Notable generator changes (non-patch)

- Listen provider type refactor — moved
`AgentV1SettingsAgentContextListenProvider{V1,V2,V2LanguageHint}` from
`resources/agent/v1/types/` → top-level `types/DeepgramListenProvider*`
and deleted `AgentV1SettingsAgentListenProvider{V1,V2}` (~400 lines
combined).
- New listen/media types: `ListenV1RequestUrl`,
`MediaTranscribeRequestOctetStream`,
`MediaTranscribeRequestDiarizeModel`;
`AsyncRawMediaClient`/`RawMediaClient` updated.
- Small updates to `Environment.java`, `RawModelsClient.java`,
`.fern/metadata.json`.

## Test plan

- [x] `./gradlew test compileExamples` passes (includes regression tests
for `maxRetries(0)`, `applyOptionsOverride`, `connectionTimeoutMs`).
- [ ] Reviewer confirms listen-provider type rename does not break
public API contract.
