The awk-based extraction had variable scoping issues when run
as a nested function. Switch to grep for finding line numbers
and sed for extraction - more reliable approach.
- Replace sed with awk for more reliable heredoc extraction
- Add debug output showing script path
- Fix restart to use lightdm instead of non-existent kiosk.service
- Kill electron process before upgrade, check electron after
- Add script path validation before extraction
- Silent upgrade: extracts app files from script without user input
- Import now shows numbered list, user can select by number
- Improved power button handler with better Electron process detection
- SIGUSR1 now primary method for power menu (more reliable)
- Upgrade automatically regenerates power button handler
- Added XAUTHORITY export for X11 authentication
