- Improved mainwindow.cpp to add a no devices detected page and integrate dependency checks.
- Cleaned up mainwindow.ui by removing unnecessary layout elements.
- Implemented check_deps.cpp and check_deps.h for verifying required dependencies on Windows.
- Created diagnose_dialog.cpp and diagnose_dialog.h for a dialog to display dependency checks.
