# What does this PR do?
- Add new /admin API (v1alpha) for administrative operations including
provider management, health checks, version info, and route listing
- Implement using FastAPI routers following batches pattern with proper
request/response models
- Endpoints: /admin/providers, /admin/providers/{id},
/admin/inspect/routes, /admin/health, /admin/version
- Create admin module structure: models.py, api.py, fastapi_routes.py,
init.py
- Add AdminImpl in llama_stack/core combining provider and inspect
functionality
- Deprecate standalone /providers and /inspect APIs (remain functional
for backward compatibility)
- Consolidate duplicate types: ProviderInfo, HealthInfo, RouteInfo, etc.
now defined once in admin.models
## Test Plan
new admin integration suite, uses generated stainless SDK, and records
new tests on this PR.
