fix: guard isConnected check against already-aborted signal

When abortSignal is already aborted at lifecycle start, onAbort() fires
synchronously and pushes connected: false. Without a lifecycleStopping
guard, the subsequent gateway.isConnected check could push a spurious
connected: true, contradicting the shutdown.

Adds !lifecycleStopping to the isConnected guard and a test verifying
no connected: true is emitted when the signal is pre-aborted.
