* feat(minimax): add image generation and TTS providers, trim TUI model list
Register MiniMax image-01 and speech-2.8 models as plugin providers for
the image_generate and TTS tools. Both resolve CN/global base URLs from
the configured model endpoint origin.
- Image generation: base64 response, aspect-ratio support, image-to-image
via subject_reference, registered for minimax and minimax-portal
- TTS: speech-2.8-turbo (default) and speech-2.8-hd, hex-encoded audio,
voice listing via get_voice API, telephony PCM support
- Add MiniMax to TTS auto-detection cascade (after ElevenLabs, before
Microsoft) and TTS config section
- Remove MiniMax-VL-01, M2, M2.1, M2.5 and variants from TUI picker;
keep M2.7 and M2.7-highspeed only (backend routing unchanged)
* feat(minimax): trim legacy model catalog to M2.7 only
Cherry-picked from temp/feat/minimax-trim-legacy-models (949ed28).
Removes MiniMax-VL-01, M2, M2.1, M2.5 and variants from the model
catalog, model order, modern model matchers, OAuth config, docs, and
tests. Keeps only M2.7 and M2.7-highspeed.
Conflicts resolved:
- provider-catalog.ts: removed MINIMAX_TUI_MODELS filter (no longer
needed since source array is now M2.7-only)
- index.ts: kept image generation + speech provider registrations
(added by this branch), moved media understanding registrations
earlier (as intended by the cherry-picked commit)
* fix(minimax): update discovery contract test to reflect M2.7-only catalog
Cherry-picked from temp/feat/minimax-trim-legacy-models (2c750cb).
* feat(minimax): add web search provider and register in plugin entry
* fix(minimax): resolve OAuth credentials for TTS speech provider
* MiniMax: remove web search and TTS providers
* fix(minimax): throw on empty images array after generation failure
* feat(minimax): add image generation provider and trim catalog to M2.7 (#54487) (thanks @liyuan97)
