SLoader Windows experimental build.

Run sloader-gui.exe.

This build includes:
- sloader-gui.exe
- sloader.exe
- Qt runtime DLLs and plugins
- bundled BaseMods: StardewProtect and SLoaderBridge

The relay server is not included in player packages. It runs only on the SLoader VPS.

Current limitation: importing mods directly from .zip is disabled in this Windows build. Extract the mod folder first, or use .smod packages.
