Pull request overview

Fixes incorrect caching behavior in the SignalR tool so runtime listings are cached (and can be returned from cache on subsequent calls).

Changes:

  • Update SignalRService.GetRuntimeAsync to cache the collected List<Runtime> instead of caching the signalRName string.
  • Add an Azure.Mcp.Server changelog entry documenting the bug fix.
