Add support for NVIDIA's API (https://integrate.api.nvidia.com/v1) with three models:
- nvidia/llama-3.1-nemotron-70b-instruct (default)
- nvidia/llama-3.3-70b-instruct
- nvidia/mistral-nemo-minitron-8b-8k-instruct
Users can configure via NVIDIA_API_KEY environment variable or auth profiles.

Switch default local embedding model from embeddinggemma-300M to
embeddinggemma-300m-qat (Quantization Aware Training). QAT models are
trained with quantization in mind, yielding better embedding quality
at the same size (Q8_0).
* fix(mattermost): add WebSocket reconnection with exponential backoff
Fixes#13980
The Mattermost WebSocket monitor had no error handling around the
reconnection loop. When connectOnce() threw (e.g. 'fetch failed' from
network issues), the error propagated through the while loop, causing
the gateway to log 'channel exited' and never restart.
Extract runWithReconnect() utility that:
- Catches thrown errors from connectFn and retries
- Uses exponential backoff (2s→4s→8s→...→60s cap)
- Resets backoff after successful connections
- Stops cleanly on abort signal
- Reports errors and reconnect delays via callbacks
* fix(mattermost): make backoff sleep abort-aware and reject on WS connect failure
* fix(mattermost): clean up abort listener on normal timeout to prevent leak
* fix(mattermost): skip error reporting when abort causes connection rejection
* fix(mattermost): use try/finally for abort listener cleanup in connectOnce
* fix: force-close WebSocket on error to prevent reconnect hang
* fix: use ws.terminate() on abort for reliable teardown during CONNECTING state
* fix(mattermost): use initial retry delay for reconnect backoff

* fix(media): recognize MP3 and M4A as voice-compatible audio
Telegram sendVoice supports OGG/Opus, MP3, and M4A, but
isVoiceCompatibleAudio only recognized OGG/Opus formats.
- Add MP3 and M4A extensions and MIME types
- Use explicit MIME set instead of substring matching
- Handle MIME parameters (e.g. 'audio/ogg; codecs=opus')
- Add test coverage for all supported and unsupported formats
* fix: narrow MIME allowlist per review feedback
Remove audio/mp4 and audio/aac from voice MIME types — too broad.
Keep only M4A-specific types (audio/x-m4a, audio/m4a).
Add audio/mp4 and audio/aac as negative test cases.
* fix: align voice compatibility and channel coverage (#15438) (thanks @azade-c)
