- New /models page with provider list (built-in + custom)
- Add provider via preset selection or custom URL with auto-fetch models
- Delete provider removes from auth.json credential_pool + config.yaml custom_providers
- Auto-switch model on add, fallback switch on delete
- Sync sidebar ModelSelector on all provider changes
- Unified provider presets in shared/providers.ts (frontend + backend)
- Backend uses hardcoded catalog first, live probe as fallback
