* feat(web,api): add fetch models and saved catalog support
Split from PR #2752 (part 2 of 3).
Backend:
- /api/models/catalog endpoint for browsing remote model catalogs
- /api/models/fetch endpoint for fetching available models from providers
- Credential reuse with provider/API base matching for security
- Default API base resolution for providers without explicit base
Frontend:
- FetchModelsDialog for importing models from remote providers
- CatalogDialog for browsing and importing from model catalogs
- Static import for FetchModelsDialog (replaces dynamic import from PR1)
- Dynamic import retained for TestModelDialog (PR3 territory)
* fix(web,api): support bare-array responses in fetchOpenAICompatibleModels
* fix(web,api): tighten maskAPIKeyValue to match maskAPIKey policy
For 9-12 character keys, maskAPIKeyValue exposed first 4 + last 4
chars (only 1 char masked for a 9-char key). Now uses the same
policy as maskAPIKey: first 3 + last 2 for 9-12 chars, first 3 +
last 4 for longer keys. Adds tests covering all key length boundaries.
* add gemini web search provider
* fix(web): prefer free providers before Gemini in auto mode
* fix(web): expose gemini api key and model settings
* fix(web): prefer configured providers before Gemini in auto mode
* fix(web): satisfy gemini lint checks
* fix(web): address gemini provider review feedback
* test(web): align auto-provider expectations
* fix(web): let gemini ignore search range
* feat: improve model configuration workflows
Add model catalog browsing, provider registry with form validation,
model fetch/test dialogs, and enhanced model management UI.
- Add model catalog API and catalog-dialog component for browsing saved models
- Add provider-registry with auto-populated form fields per provider
- Add provider-combobox, fetch-models-dialog, test-model-dialog components
- Add model-validation for provider-aware model ID validation
- Add command and popover UI components
- Enhance edit-model-sheet with tool schema transform support
- Add anthropic to protocolMetaByName for correct default API base
- Apply NormalizeBaseURL to anthropic provider for consistent URL handling
- Add i18n keys for new model management features (en/zh)
* fix(web): prevent auto-fetch when API key is missing in fetch models dialog
When a provider requires an API key but none is set, the dialog now shows
the warning without triggering a doomed fetch attempt. Fetch is deferred
until the user provides a key.
* fix(web): add credential warning for catalog imports from remote providers
When importing models from a catalog entry whose provider requires an API
key, a yellow warning banner now informs users that credentials will need
to be configured after import.
* feat(web,api): test connection with real connectivity verification and unsaved form values
Add POST /api/models/test-inline endpoint that performs actual network
probes (GET /models) instead of just checking config. Frontend Test
Connection now uses current form values (not saved state) and is
available in both Add and Edit model flows.
* style(web): apply linter formatting across model config components
Normalize quote style, import ordering, and class name ordering as
reported by the project linter.
* fix(web,api): fix edit test connection false negative and gate fetch for unsupported providers
- handleTestInlineModel now accepts optional model_index to fall back to stored credentials when api_key is empty, fixing false negatives when testing edited models
- Add supportsFetch to provider registry and FETCHABLE_PROVIDER_KEYS derived set
- Gate Fetch Models button to only show for OpenAI-compatible and Ollama providers
- Add backend guard in handleFetchModels to reject unsupported providers with clear error
* fix: address review feedback on model config workflow
- Send explicit {} for empty extra_body/custom_headers fields so the
backend clears stored values instead of preserving them
- Merge backend provider_options with frontend PROVIDERS registry so
the provider picker reflects backend-supported providers and policy
fields (create_allowed, default_auth_method, auth_method_locked)
- Render provider combobox popover inside the sheet scroll container
to fix wheel events scrolling the sheet instead of the provider list
* feat(web,api): add provider selection, model form foundation, and validation
Split from PR #2752 (part 1 of 3).
Backend:
- CRUD model endpoints (list/add/update/delete/set-default)
- Provider metadata with default API bases and model provider options
- Model ID validation and normalization
- Anthropic default API base normalization
Frontend:
- Provider registry with metadata, labels, icons, and aliases
- Provider combobox with backend option merging
- Model field validation with provider-aware checks
- Redesigned add/edit model sheets with provider selection
- Dynamic imports for fetch/catalog/test dialogs (coming in PR2/PR3)
- i18n support for model configuration UI

* Handle MCP sse and URL-based server mapping
* Validate duplicate MCP server names before save
* Disable MCP discovery options based on mutual exclusivity in config section
