Anthony Tafoya 826b6e8199 Reuse cloud plugin catalogs across turns until invalidated (#61386) ...

## Why

Cloud plugin discovery previously ran each turn even when authentication and Apps resources were unchanged.

## What changed

- Reuse complete, warning-free catalogs across turns, including empty catalogs, while authentication and the Apps resource cache key match.
- Retry partial catalogs and catalogs with warnings on subsequent turns, preserving failure backoff.
- Reject discovery results if authentication or Apps resources changed while discovery was in flight. Hosts must invalidate Apps resources when the remote plugin catalog changes.

## Testing

Extend lifecycle tests to cover populated and empty cache reuse, resource and auth invalidation during discovery, and reuse of the empty catalog after plugin revocation.
