Description

This PR improves Linux desktop integration and fixes several issues related to environment setup and user experience.

Changes

Linux Environment Fixes

• Fix JAVA_HOME not being set on Linux: Ensures JAVA_HOME environment variable is properly set when executing batch files on Windows, and extends this fix to Linux systems to ensure Java-based tools (Apktool, JADX, etc.) can find Java correctly.

User Interface Improvements

• Show open project name in window title: The main window title now displays the currently open project name, making it easier to identify which project is active when multiple instances or projects are open.

Linux Desktop Integration

• Create desktop entry on Linux: Automatically creates a .desktop file on first launch (with user permission) to enable proper integration with Linux desktop environments, allowing the application to appear in application menus and docks.
• Update desktop database async: Desktop database updates are now performed asynchronously using a worker thread to prevent UI blocking during the update process.

Window Management

• Set window icon from main window: Ensures the window icon is properly set from the main window, improving visual consistency across different desktop environments.

Technical Details

• Desktop file creation includes proper icon theme integration (hicolor theme structure)
• Icon cache is automatically updated after icon installation
• Desktop file includes proper StartupWMClass for correct window matching
• All desktop integration operations are non-blocking to maintain UI responsiveness

Testing

• Tested on Ubuntu with GNOME desktop environment
• Verified desktop entry appears in application menu
• Confirmed icon displays correctly in dock and application menu
• Tested with multiple projects to verify window title updates
