Both projects ship official standalone Linux AppImages separate from
the esde/retroarch Wolf catalog containers this repo already runs.
Adding either one to Steam as a non-Steam game (steam-add-nonsteam-game,
now reaching the same roms/saves/bios/retro-home/retroarch mounts as
the esde/retroarch containers) lets Steam Input assign a 4th controller
its own identity by device path, past Wolf's 3-concrete-pad-type ceiling.
ES-DE is hosted on GitLab rather than GitHub, so this adds a GitLab
Releases API counterpart to the existing GitHub-based download helper.
RetroArch's own buildbot doesn't publish through either API, so this
uses hizzlekizzle/RetroArch-AppImage, the community nightly-build
project the AppImage catalogs themselves point to (flagged as
third-party, same treatment this file already gives the Dolphin
community build). Both downloads are opt-in (default no) and symlink
to a fixed filename so steam-add-nonsteam-game's case-sensitive
substring match finds them regardless of the vendor's own asset name.
