Felitendo b17ec7b0b0 lunar-client-bin: add package (3.7.12-1)
Upstream moved to an "ow" electron-updater channel with a filename
suffix; latest_version checks both channels (vercmp picks the winner) and
refresh_checksums keeps the _appimage filename in sync. Also clean up
downloaded .AppImage files like the other source leftovers.

# lunar-client-bin - Lunar Client (https://lunarclient.com), Minecraft PvP
# modpack launcher, proprietary Electron AppImage.
#
# Upstream hosts versioned AppImages itself, so there is no build_artifact():
# on a new version pkgver, the artifact filename (_appimage) and the checksum
# are refreshed. Upstream currently publishes on the "ow" electron-updater
# channel (latest-ow-linux.yml) with an -ow filename suffix; the old plain
# channel (latest-linux.yml) went stale but is still checked in case they
# switch back - whichever carries the higher version wins.
