Some vendors publish a release feed of their own that is faster and more
precise than anyone's packaging of it. A package opts in with an
.omarchy/upstream.sh hook that reports the newest release as JSON, and the
driver rewrites pkgver, the checksum arrays the hook names, and pkgrel.
Writes are guarded on both ends: every assignment the update will touch is
verified to exist before anything is written, so a hook naming an array the
PKGBUILD lacks fails with the file untouched rather than half rewritten; and
pkgver is held to pacman's character set, because it lands in a file makepkg
sources as shell.
Ordering is vercmp's, not sort -V's -- they disagree about whether 1.0a
precedes 1.0, and pacman is what decides if a published package is an upgrade.
That is also why the workflow runs in an Arch container rather than straight on
the runner.
