Wire .gitea/scripts/check-already-published.sh into every job in
build.yml. New step `skip if already published` (id: skip-check) lands
right after actions/checkout@v4 and runs the helper against the job's
recipe-dir. Subsequent steps gain `if: steps.skip-check.outputs.skip
!= '1'`, except `wipe secrets` which keeps its existing
`if: always()`.
Recipe-dir per job is taken from each job's existing `cp -r arch/...`
or `cd debian/...` line — no guessing.
Effect: on push where only e.g. firefox-fourier changed, 13 jobs HEAD
the pool, see 200, and short-circuit; only firefox-fourier rebuilds.
Verified live against packages.reauktion.de — current branch tip
would skip 10/14 jobs.
Patch is text-based (no PyYAML round-trip) so comments and blank
lines stay where they were. Diff is 190 lines added, 0 removed.
