Replaced PyQt4 imports with Extensions.qt_bindings for consistency across the codebase. Updated margin settings to use contentsMargins for improved layout management. Changed dialog execution methods to use exec() instead of exec_() for compatibility with newer Qt versions. This enhances the overall maintainability and performance of the UI components.

Migrate the codebase from PyQt4 to PyQt6 via the qt_bindings compatibility
layer (enum flattening, signal/slot, QScintilla scoped enums, dialog/return
value shims) and fix Python 3.11 issues in vendored libs (cx_Freeze opcodes,
autopep8/pep8 getargspec, re.LOCALE).

Add scripts/exercise_editor.py, a headless (offscreen) smoke test that
exercises project create/load, editor, run/output, completion, find/replace,
find-in-files, settings, library, project view, rope rename, snippets, and
export. Wire it into GitHub Actions (.github/workflows/smoke.yml).

Tokenize StyleSheet into Light/Dark palettes and add a Theme
(Light/Dark/System) setting with live switching plus a matching QPalette so
native surfaces follow the theme. Drop blurry PNG sub-control arrows/close
icons so Qt draws crisp, HiDPI-friendly native ones.

Add a Ctrl+Shift+P command palette (fuzzy filter, keyboard nav) exposing
project/navigation/theme/about commands. Polish the top bar with an app
logo + title and button tooltips. Start screen now uses a cross-platform
fixed font, an empty-state for recent projects, and theme-aware colors.

Fix the project-tree selection row-jump (drop font resize) and replace the
red menu hover with the accent color. Extend the headless smoke test with
command-palette and theme guards.
