List models

Lists the TTS and STT models available through AllModels. Each model includes accepted aliases, supported providers, and whether it can be used for streaming or synchronous requests (with an orthogonal `batch` flag for STT providers that queue internally).

Liveness probe GET

Returns `{ "ok": true }` and the deployed Git commit when the API is available. The commit is null when it was not injected at deployment. No authentication required.

List providers GET

Lists available providers, their default models and voices, and the TTS and STT models they support. Use `GET /v1/models` to browse by model instead.
