Merge GPU preference feature branch to main branch version 2.0.2 for testing (#3)

* modernized UI for GPU Preference option

* feat: auto-detect dedicated GPU on hybrid laptops (iGPU+dGPU)

* feat: detailed GPU info in auto-detection feature on startup

* feat: add GPU options for launcher

- Add GPU preference setting (Auto/Integrated/Dedicated)
- Implement Linux GPU selection with DRI_PRIME and NVIDIA env vars
- Add GPU detection using Electron's app.getGPUInfo()
- Update settings UI with GPU preference dropdown
- Integrate GPU preference into game launch process

* feat: auto-detect dedicated GPU on hybrid laptops (iGPU+dGPU)

* added fallbacks to and option to use integrated GPU.

* add package-lock and fix deps version

* changed 'Nvidia' string to 'NVIDIA'

* fix: selecting `dedicated` option while using nvidia GPU did not set its specific env variables

* remove unused `CONFIG_FILE` variable on launcher core modules

* fix: duplicated save-load gpu detection functions

* move game option settings to the top, while custom java to the bottom

* fix: settings-header margin-bottom from 3rem to 1rem and supress line-clamp warning
