- Update `Configuration` to use C++ vector instead of C arrays - Rename `Desktop` app to `Launcher` - Fix for hard-coded app start of `Launcher` and `CrashDiagnostics` apps. - Ensure `Launcher` icons are clickable, even if they're not loading. - Don't show error scenario for SD card in statusbar when SD card status is unknown (this happens during Mutex timeout due to LVGL rendering delays) - Cleanup deprecated `Mutex` methods. - `hal::getConfiguration()` now returns a pointer instead of a reference, just like `tt:getConfiguration()`
