@livekit/agents-plugin-openai@1.4.7

### Patch Changes

-   Fix DataStream avatars (Anam, Bey, D-ID, LemonSlice, Runway, Tavus, Trugen) stalling the - [#1795](https://github.com/livekit/agents-js/pull/1795) ([@smorimoto](https://github.com/smorimoto))
    conversation on user interruption when paired with the OpenAI Realtime API.

    `DataStreamAudioOutput` parsed the `lk.playback_finished` RPC payload with a compile-time-only
    `as PlaybackFinishedEvent` cast. The LiveKit avatar protocol serializes that payload with
    snake_case keys (`playback_position`, `synchronized_transcript`) — confirmed against Anam's
    live engine, which emits `{"playback_position": 2.0, "interrupted": true, "synchronized_transcript": null}`
    — so the camelCase `playbackPosition` read back `undefined`. That became
    `Math.floor(undefined * 1000) === NaN`, which `JSON.stringify` serializes as `null` in
    `conversation.item.truncate`; the OpenAI Realtime API then rejected the truncate with an
    `invalid_type` error and the interrupted turn could not recover.

    `DataStreamAudioOutput` now normalizes the wire payload (snake_case primary, camelCase
    fallback), which also restores the previously-dropped `synchronizedTranscript` on interrupted
    turns. As defense-in-depth, the realtime truncate path now clamps a non-finite `audioEndMs` to
    a valid non-negative integer in both `AgentActivity` and the OpenAI plugin so a malformed or
    absent playback position can never again serialize as `null`.

-   Fix `openai` realtime STT (transcription session) failing on every model - [#1767](https://github.com/livekit/agents-js/pull/1767) ([@tsushanth](https://github.com/tsushanth))
    with `invalid_request_error.invalid_model` when connecting directly to
    `wss://api.openai.com/.../realtime`.

    OpenAI's native endpoint now treats a `?model=` query param on the
    WebSocket upgrade URL as selecting a conversation session, so the
    subsequent transcription-mode `session.update` is rejected — surfacing
    as `invalid_model` and a `4000` close. Drop the `?model=` parameter
    when the host is `api.openai.com` (the model is conveyed via
    `session.update → audio.input.transcription.model` instead).

    OpenAI-compatible proxies (LiteLLM, Cloudflare AI Gateway, etc.) still
    receive the model on the upgrade URL so they can route by model before
    the first frame, preserving the original intent of #1467.
