Wayland does not expose absolute pointer coordinates to clients,
so we cannot reliably detect which monitor has focus. Instead,
show the full lockscreen UI on every monitor — the compositor
assigns keyboard focus to the surface under the pointer via
ext-session-lock-v1.
Share a single FingerprintListener across all windows to avoid
multiple device claims. Also add makepkg build artifacts to
gitignore.
Add Arch Linux PKGBUILD for makepkg installation. Installs the
Python package, PAM config, and example config file. Fix pkgver()
to handle repos without tags (sed always exits 0 on empty input).
Remove leftover moongreet icon that was accidentally included in
the data directory.
