/**
 * MiniMax TTS provider — async task model (submit → poll → download).
 *
 * MiniMax's t2a_async_v2 endpoint does not match the OpenAI POST /audio/speech
 * shape (it returns task_id, then we poll, then we fetch the file by file_id),
 * so we implement the contract directly rather than using
 * createOpenAiCompatibleSpeechProvider.
 *
 * Implementation notes (per docs/voice-rearchitecture.md §8.4.4):
 *   - Default per-call timeout: 150s. Submit + poll + download can legitimately
 *     take 60-120s on long inputs, so we enforce `Math.max(timeoutMs, 150000)`.
 *   - `synthesizeStream` is intentionally not implemented. MiniMax has a
 *     separate WebSocket streaming endpoint that does not match the
 *     buffer-then-wrap pattern; speak-core falls back to wrapBufferAsStream.
 *   - Poll interval = 2s, max 60 attempts (2 min cap). Aligns with MiniMax docs.
 *   - `groupId` is read from config but not passed into the request body —
 *     MiniMax embeds groupId in the API key for this account tier. Kept as a
 *     forward-compat slot for the enterprise account tier.
