fix: Lazy GTK imports for better pip/pipx compatibility (#49)
* fix: Lazy GTK imports for better pip/pipx compatibility - Move GTK-dependent imports (tray_indicator) inside main() function - Import after check_dependencies() so users get helpful error messages - Update ui/__init__.py to not import tray_indicator at module level - Update vocalinux/__init__.py to not import GTK-dependent modules - Improved error messages for pip/pipx users with missing GTK typelibs - Bump version to 0.2.1-alpha This fixes the 'Namespace AppIndicator3 not available' error that pip/pipx users encounter because PyGObject can't find system typelibs. Closes #47 * test: simplify settings dialog tests * style: fix lazy import ordering
