makepkg --printsrcinfo does not run pkgver(), so the -git .SRCINFO kept
the version from when the package was created and push.sh never had a
change to publish. update.sh now runs makepkg -od --noprepare first so
pkgver() writes the current git describe version into the PKGBUILD.
packaging/aur/ now holds the full content of three AUR repositories:
proton-drive-for-linux builds the latest tag from source,
proton-drive-for-linux-git builds main, and proton-drive-for-linux-bin
installs the binaries attached to the GitHub release. Each carries a
PKGBUILD, a generated .SRCINFO, an ignore-everything .gitignore, and the
0BSD license the AUR expects for package sources.
update.sh bumps the release-based packages and regenerates the .SRCINFO
files; push.sh publishes each package to its AUR remote. The README now
points users at the AUR packages and keeps the in-tree PKGBUILD as the
development build.
