Update Qt Designer sample editor to PyQt6
Migrate the qt-designer-python sample text editor from PyQt5 to PyQt6 to match the refreshed tutorial: - Regenerate main_window_ui.py with pyuic6 (PyQt6 6.11.0) - Update app.py imports to PyQt6 (QtWidgets and uic) - Update README install instructions to PyQt6 Verified: the app builds its GUI (setupUi) and loads find_replace.ui via uic.loadUi() under PyQt6 on Python 3.14.
