Replaces the single-host local model settings page with a full model
registry interface at /settings/local.
Hosts section:
- List existing hosts with inline edit + save + remove
- Collapsible "Add host" form
- Per-host "Fetch models" button
Models section:
- List all models with label, model name, host, context_k badge, tags
- Remove button
Add Model section:
- Host dropdown, label, model name, context_k, tags (comma-separated)
- "Fetch models from host" with auto-fill picker
Role Assignments section:
- One row per defined role (chat, orchestrator, distill, coder, research)
- Primary + backup_1 + backup_2 dropdowns per role
- Dropdowns pre-filled from registry on load
- AJAX save on change (POST /api/models/role) with toast confirmation
- Built-in models (claude_cli, gemini_cli, gemini_api) always available in dropdowns
Backend:
- All user_settings references replaced with model_registry
- host/{id}/remove route added
- fetch-models now accepts host_id query param
- POST /api/models/role for AJAX role assignment
