Document the supported provider search terms.

orchestrator_capabilities exposes OrchestratorMcpCapabilitiesInput to MCP callers, but its search description mentions only model IDs and labels. The implementation also accepts provider instance IDs, drivers, display names, and subProvider. Callers relying on the schema may not discover these searches.

Suggested fix 
-      description: "Match model ids and labels. Replaces the short list.",
+      description:
+        "Match provider instance ids, drivers, display names, model ids, labels, and subProvider. Replaces the short list.",

This documentation fix is separate from the existing filtering tests.

307 - 313:
Update the search description in OrchestratorMcpCapabilitiesInput to document
that searches match provider instance IDs, drivers, display names, model IDs,
labels, and subProvider. Keep the existing short-list replacement behavior
documented.
