[undermirrors]

• Try to load wallpaper when a new screen is plugged, if it was save previously

Pull Request Overview

This PR refactors the IPC system to distinguish between external and internal requests using the subenum crate, adds a profile manager for persisting wallpaper configurations, and migrates from crossbeam channels to standard library mpsc channels.

Key changes:

• Introduces InternalRequest enum with subenum to generate IPCRequest as a subset, enabling internal-only messages like NewOutput
• Adds ProfileManager to save/load wallpaper configurations per screen
• Replaces crossbeam::channel with std::sync::mpsc throughout the daemon
