feat(macOS): enable cross app update

[deepak1556]

Fixes #308646

ICrossAppIPCService:
- Owns the single crossAppIPC connection for the application
- Exposes onDidConnect, onDidDisconnect, onDidReceiveMessage events

Secret sharing refactoring:
- MacOSCrossAppSecretSharing now takes ICrossAppIPCService instead of
  creating its own crossAppIPC connection

Pull request overview

Enables macOS cross-app update coordination for the Agents app (mirroring existing Windows behavior) by introducing a shared cross-app IPC service and refactoring existing crossAppIPC consumers to use it.

Changes:

• Enable cross-app update coordinator on macOS (insider/exploration) in the Agents UI and app bootstrap.
• Introduce ICrossAppIPCService to own a single crossAppIPC connection and expose connect/disconnect/message events.
• Refactor CrossAppUpdateCoordinator and MacOSCrossAppSecretSharing to consume ICrossAppIPCService instead of creating their own connections.

• initializeAsHostApp checks crossAppIPCService.available, but available is currently false unless CrossAppIPCService.initialize() has already been called somewhere else. This makes host-side secret sharing a no-op when the update coordinator path doesn’t run (e.g. non-insider/exploration). Ensure the IPC service is initialized before checking availability / registering message handlers so the host can actually respond to SecretRequest.

		if (!this.crossAppIPCService.available) {
			this.logService.info('[CrossAppSecretSharing] crossAppIPC not available');
			onComplete?.();
			return;
		}
