* refactor: use Twilight AI SDK for model and provider connectivity testing
Replace hand-rolled HTTP probing with the Twilight AI SDK's built-in
Provider.Test() and TestModel() methods.
- Model test now runs Provider.Test() (connectivity + auth) followed by
TestModel() (model availability) via the SDK
- Provider test auto-detects client_type from associated models and
creates the correct SDK provider for accurate auth header handling
- Embedding models use a dedicated /embeddings endpoint probe since
the SDK's chat Provider doesn't cover embedding APIs
- Latency measurement now covers the full test lifecycle
- Add TestStatusModelNotSupported for models not found by the provider
- Upgrade twilight-ai to v0.3.3-0.20260321100646-43c789b701dd which
includes fallback probing for providers without GET /models/{id}
* fix: lint
* feat(models): add per-model probe testing and auto-detect in UI
Move health probes from provider level to model level for precise
testing with real model_id and client_type. Provider test is now a
simple reachability check.
Backend:
- Add POST /models/:id/test endpoint that probes the model's provider
using its actual model_id and client_type
- Add model healthcheck checker for bot health checks (chat/memory/embedding)
- Simplify provider test to reachability-only
Frontend:
- Auto-probe models on mount with status indicator (green/yellow/red dot + latency)
- Auto-probe provider reachability on load and on provider switch
- Fix missing faBolt icon registration
- Manual re-probe via refresh button
Closes#117
* fix(models): increase probe timeout to 15s for slow providers
Some providers (e.g. DashScope) exceed the 5s probe timeout, causing
false-negative "context deadline exceeded" errors. Increase per-probe
timeout to 15s and healthcheck overall timeout to 30s.
* fix(sdk): regenerate exports after merge conflict
Resolve duplicate SDK exports introduced by merge conflict resolution so the web build can compile again while preserving new model probe endpoints.
