hyprmoncfg: Multi-Monitor Manager for Omarchy

Plug your monitors in and the right layout comes back. Save a profile per setup and hyprmoncfg applies it automatically on hotplug, on lid open and close, and after suspend. Layout editor with per-display brightness, snapping, per-output scale and sharpness checking, HDR, wide gamut and ICC colour management, mirroring, rotation, and a workspace planner. Profiles match monitors by make, model and serial rather than the port they are plugged into, so moving a cable does not break your layout.
