Group A: source upstream binaries instead of self-built artifacts

The AUR does not allow packages to ship a binary tarball built by the
maintainer - a -bin package must repackage a deliverable published by
upstream. These six packages now do that:

  snapx-bin            upstream's self-contained Linux tar.zst
  zapzap-bin           upstream's pure-Python wheel
  faugus-launcher-bin  upstream's arch-independent .deb
  wiiudownloader-bin   upstream's AppImage
  waydroid-helper-bin  upstream's AppImage
  chiaki-ng-bin        upstream's AppImage

All six drop build_artifact() and switch to refresh_checksums(), so CI no
longer builds or hosts anything - it only tracks upstream's assets.

Where the asset name carries build metadata that does not follow from
pkgver (snapx, faugus-launcher), refresh_checksums() resolves it via the
GitHub API and syncs an _asset variable in the PKGBUILD.

Dependency lists are re-derived from what the bundles actually resolve
outside themselves; the AppImage payloads land in /opt with wrappers in
/usr/bin, because their entry points resolve paths relative to argv[0].
