FastAPI route change

Use this skill when adding or modifying a FastAPI route under gtex_link/api/routes/.

Checklist

1. Request model. Define or extend a Pydantic model in gtex_link/models/requests.py. Field aliases map to GTEx Portal query parameters. Set sensible defaults and validators.
2. Response model. Define or extend the matching response model in gtex_link/models/responses.py. Match upstream field names.
3. Service method. Add or update a method on GTExService in gtex_link/services/gtex_service.py. Wrap upstream calls in the existing caching/rate-limiting paths. Do not bypass GTExClient.
4. Route handler. Add the route in the appropriate file under gtex_link/api/routes/. Reuse FastAPI Depends for GTExService. Return the Pydantic response model.
5. Tests.
   • Route test under tests/test_api/test_<category>_routes.py using respx to stub https://gtexportal.org/api/v2/....
   • Service test under tests/test_services/ for the new service method.
6. Docs. If the route exposes a new GTEx endpoint, update docs/README.md and add per-endpoint markdown via python docs/generate_endpoint_docs.py when the openapi spec is updated.
7. MCP exposure. Decide if this should be an MCP tool (see mcp-tool-change skill if yes).
8. CI. Run make ci-local before pushing.
