v0.4.0

✨ Features

• add Steam shortcuts for installed apps, fix Gear Lever detection (moi952)
  • Add/remove an installed Flatpak or AppImage as a native Steam shortcut
    right from its detail page, with the correct icon/artwork and a
    restart-Steam prompt afterward
  • Live shortcuts.vdf detection so the button never offers to re-add a
    shortcut that's already there, including one added manually or by the
    system's own Flatpak integration
  • Rename the app detail page's "Remove" button to "Uninstall" (all 15
    languages) so it's no longer confused with the new shortcut button
  • Fix Gear Lever install/uninstall state going stale: list_apps() now
    re-verifies it live even on its cached fast path, instead of trusting
    a snapshot that can survive a Steam/plugin restart untouched
  • Work around flatpak install --system hanging forever past a
    successful install (flatpak-system-helper holding the subprocess's
    stdout/stderr open) by not capturing output for that call
  • Gear Lever install notice: match other cards' sizing, horizontal
    button navigation, a non-overflowing progress bar, and buttons that
    share the row's full width proportionally to their own label length
