Fix Qt compatibility and VM script docs

Updates desktop shell and application code for cross-Qt compatibility: uses begin/endFilterChange for Qt 6.10+, gates LayerShell usage to Qt < 6.5, and adds include handling for generated QML type registration files so nebula-shell builds reliably. Also fixes qInfo size formatting casts and updates README commands to invoke run-sway-vm.sh via `sh` for more portable execution.
