Forward errors to CLI when using tophatctl

[lfroms]

What does this change accomplish?

This change updates how errors are displayed when using tophatctl. Previously, tophatctl was purely a remote control for the UI, so all errors were displayed as AppKit alerts. With this change, errors are no longer displayed in the UI for tophatctl-triggered operations and are instead printed to the command line, along with nonzero exit code.

How have you achieved it?

• By using InstallCoordinator directly in remoteControlReceiver delegate methods since InstallAppAction is purely for UI-initiated installs.
• By extracting some recipe constructing logic into extensions to avoid duplicating between delegate method implementations and the InstallAppAction.
• By extracting the error message formatting logic into a shared type so that the existing ErrorNotifier and RemoteControlReceiver (which now returns the error messages in the reply) can both use it.
• By updating the receiver and Install command accordingly to send/receive the error data.

How can the change be tested?

Run tophatctl with input that will cause installation to fail and ensure that the error message is printed to the CLI with nonzero exit. Also ensure that existing installation flows that produce error (especially UI-initiated) are still working and display errors in UI alerts.
