Master HUD

The UI rendering backbone of the Realistic Farming mod ecosystem. MasterHUD owns the single draw loop that renders every companion mod's overlay, using a pull model with dirty flags – companion mods flag their HUD data as dirty instead of rebuilding strings every frame, and MasterHUD calls their fetch callback only when the data actually changed. It also handles menu-suspend, corner stacking, and clean unload once for all of them. There are no settings to configure – simply install it, keep it loaded, and let the companion mods make use of it.
