Refactor GPU config: move critical Linux flags to main.js

Critical Linux and SteamOS GPU flags are now set immediately after loading Electron in main.js, before app.ready, to ensure proper rendering and compatibility. The GPUConfig class now only applies additional, non-critical settings. Improved SteamOS detection logic and added more detailed logging for GPU environment detection.
