v0.2.2 - Shutdown Fix

Fixes

• Actually fixed server hanging on Ctrl+C — replaced await using with explicit dispose bounded to 3 seconds, so a stuck HubConnection can no longer block shutdown
• Reduced host shutdown timeout from 30s (default) to 5s
• Caught OperationCanceledException in the directory service reconnect loop so cancellation exits immediately instead of propagating through dispose
