feat: Additive merge of webui branch with PyQt GUI support
- Add abogen/pyqt/ package with full PyQt6 desktop GUI - Restore PyQt GUI files (gui.py, book_handler.py, queue_manager_gui.py, voice_formula_gui.py, conversion.py) - Add new shared modules from webui: book_parser.py, subtitle_utils.py, spacy_utils.py - Add Linux libraries (libxcb-cursor) for Qt platform plugin support - Add new epub parsing tests from webui branch - Update pyproject.toml with dual entry points: - abogen: PyQt6 desktop GUI - abogen-web: Flask Web UI - Add PyQt6 to dependencies - Re-export PyQt classes from root modules for backwards compatibility - Merge CHANGELOG.md entries (1.2.0-1.2.5 from webui) - Update README.md with dual interface documentation Implements #26 - shared core with separate UI folders
