CI currently rebuilds every recipe on every push. distcc-avahi hasn't
changed in weeks but still burns runner-time. Add a small bash helper
that takes a recipe dir (arch/<n> or debian/<n>), resolves the expected
pool URL on packages.reauktion.de, and prints `skip=1` or `skip=0`.
Live-tested against all 14 recipes. Sources PKGBUILDs in a sandboxed
subshell so epoch=, ${_pkgver/-/}, and pkgname=() arrays resolve
correctly. For debian/*, extracts top-level PKGVER/PKGREL lines with
an awk guard that rejects command-subst and embedded-command
assignments (avoids false-positive matches against HEREDOC-quoted
dkms.conf content).
Wiring into build.yml lands in the next commit.
