* refactor: support explicit model list providers
* fix(web): preserve explicit model providers
* fix(web): preserve legacy provider prefixes on model updates
fix(models): normalize explicit provider-prefixed ids
fix(api): preserve legacy model updates across providers
fix(agent): preserve config identity for explicit provider refs
* fix ci
* fix(api): enhance model availability probing with backoff and caching mechanisms
* fix(lint): resolve gci and predeclared issues in model probe
* fix(api): address copilot review feedback on probe cache key and test stability
* fix(api): reduce probe cache key fragmentation
* feat(web): clarify model availability and status display
- Rename model availability field from configured to available across backend API and frontend usage
- Keep status as reason classification (configured/unconfigured/unreachable) and show unreachable in UI
- Preserve API key preview even when local service is unreachable
- Update backend tests to assert both availability and status semantics
* fix(web): clarify unreachable model status and wording
- Show unreachable status in model cards instead of API key preview when service is down
- Keep API key placeholder preview in model settings whenever an API key is already saved
- Rename model status wording from configured to available across backend, frontend, and i18n
- Update backend model status tests to match renamed status semantics
* style(web): standardize formatting in handleListModels function
* refactor(web): enforce status field as required to follow backend behavior
* feat(provider): add lmstudio vendor and local no-key behavior
* refactor(provider): consolidate protocol metadata and local tests
* fix(provider): sync lmstudio probing and model normalization
* test(web): format lmstudio model status cases for golines
* Improve the web launcher and gateway integration across backend and frontend.
- add runtime model availability checks for local and OAuth-backed models
- support launcher-driven gateway host overrides and websocket URL resolution
- add gateway log clearing and keep incremental log sync consistent after resets
- migrate session history APIs to JSONL metadata-backed storage with legacy fallback
- expose session titles and improve chat history loading and error handling
- move shared backend runtime helpers into the web utils package
- avoid blocking web startup when automatic onboard initialization fails
- add backend tests covering gateway readiness, host resolution, models, logs, and sessions
* feat(agent): add skills and tools management APIs and UI
- add backend APIs to list, view, import, and delete skills
- add tool status and toggle endpoints with dependency-aware config updates
- add agent skills/tools pages, routes, sidebar entries, and i18n strings
- add backend tests for the new skills and tools flows
* chore(frontend): upgrade shadcn to 4.0.5 and refresh lockfile
* chore(web): keep backend dist placeholder tracked
