Comprehensive AutoInstaller GUI fixes and improvements

Mount Operations Fix:
- Add graceful error handling for mount operations in configure_target_system()
- Handle 'already mounted' errors common in live systems
- Continue installation despite mount failures instead of crashing
- Ensure mount point directories exist before mounting
- Update unmount operations with similar error handling

Progress Tracking Enhancement:
- Re-estimate copy progress every 10 seconds based on actual transfer rate
- Display real-time speed, ETA, and remaining data in progress text area
- Use dynamic rate calculation instead of static time-based estimation
- Better accuracy for long-running copy operations

Build Process Optimization:
- Move AutoInstaller GUI build to early stage of ISO build process
- Ensure binary is included in the live system within the ISO
- Remove duplicate build section from end of script
- Add confirmation messages that binary is included in ISO

Code Quality Improvements:
- Fix AttributeError: 'network_label' -> 'interface_label' in set_defaults()
- Remove incorrect PyInstaller hidden imports (QShortcut, QKeySequence)
- Update documentation and README files with recent fixes
- Better error handling throughout the installation process

+- ✅ **Clean Environment Execution** - Isolated subprocess calls for system command reliability
+- ✅ **Dynamic Progress Updates** - Real-time rsync output parsing and display
+- ✅ **Build System Integration** - Automatic GUI binary build and inclusion in live system
+
+### 📝 **Files Modified/Added**
+- **Added:** [`autoinstaller_gui/`](autoinstaller_gui/) - Complete GUI installer directory
+- **Added:** [`autoinstaller_gui/autoinstallergui.py`](autoinstaller_gui/autoinstallergui.py) - Main GUI application
+- **Added:** [`autoinstaller_gui/build_autoinstaller_gui.py`](autoinstaller_gui/build_autoinstaller_gui.py) - PyInstaller build script
+- **Added:** [`autoinstaller_gui/README.md`](autoinstaller_gui/README.md) - GUI-specific documentation
+- **Modified:** [`config/includes.chroot/root/.xinitrc`](config/includes.chroot/root/.xinitrc) - GUI preference over script
+- **Modified:** [`build.sh`](build.sh) - Automatic GUI binary build integration
+- **Modified:** [`cleanup.sh`](cleanup.sh) - GUI cleanup integration
+
+### 🎯 **Impact**

 ## Version 2.0.1 - Password Logic Fix (2025-09-06)
 
 ### 🐛 Critical Bug Fix

TODO.md

-# TODO List
-
-## AutoInstaller GUI Improvements
-
-### Copy System Step Enhancement
-- **autoinstaller_gui**: Add more details in the copy system step
-- Show shell command outputs in a small text area during rsync operation
-- Display real-time progress of file copying with current file/directory being processed
-- Show transfer statistics (files copied, data transferred, speed)
-
-### Network Configuration Timing
-- **autoinstaller_gui**: Try to set `/target/etc/network/interfaces` before mounting
-- Move network configuration file creation to happen before disk mounting
-- Ensure network interfaces file is written to target filesystem before mount operation
-- Test that network configuration persists correctly when written pre-mount
-
-## Live System Fixes
-
-### Profile.d File Cleanup
-- **live system**: Remove duplicate startx zz-live file in `/etc/profile.d`
-- Check for duplicate `/etc/profile.d/zz-live-config_xinit.sh` entries
-- Clean up redundant live configuration files
-- Ensure only one instance of startx configuration exists
-
-## Implementation Notes
-- All changes should maintain backward compatibility
-- Test on both live USB and installed systems
-- Ensure proper error handling for all new features
-- Update documentation after implementing changes
