v1.8.0

Added

• About dialog enriched — now shows Python version, PySide6 version, platform string, and author(s) as clickable mailto: links read from package metadata.
• Menu icons — all menu-bar actions (File, Catalog, Images, Settings, Help) now display icons; new SVG assets created for Quit, Duplicate, Refresh, Catalog configuration, History, Program settings, Keyboard shortcuts, and About.
• Context menu icons — the file-list context menu reuses the same QAction objects as the Images menu, ensuring identical icons, labels, shortcuts and enabled/disabled state at all times.
• ui/icons.py — shared get_icon(svg_name, theme_name, text_fallback) helper that resolves icons via FreeDesktop theme → bundled SVG → text fallback; consolidates previously duplicated logic from image_viewer.py.
• Keyboard shortcuts dialog — added missing entries: Ctrl+Z (Undo rename), Ctrl+O (Open), Ctrl+Shift+O (Open with), Ctrl+N (New catalog), Ctrl+Shift+D (Duplicate catalog); Del and Escape now rendered via QKeySequence.toString(NativeText) for correct localisation.
• Undo rename shortcut — Ctrl+Z activates the Undo rename button.

Changed

• Version read from package metadata — importlib.metadata replaces the hardcoded version string in __main__.py; the About dialog always shows the installed version.
• Context menu selects clicked row — right-clicking an unselected row now selects it before the menu appears, so actions operate on the expected file.

Fixed

• PyInstaller bundle crash on startup — email was listed in excludes but is required by importlib.metadata at import time and by email.utils in the About dialog; removed from excludes.
• Menu icons missing in PyInstaller bundle — _RESOURCE_DIR in ui/icons.py was computed from __file__, which points inside the package directory in the bundle; now uses sys._MEIPASS when available, matching the actual extraction path of bundled SVG assets.
