- tests: match localrepo packages by exact name (foo no longer satisfied
by foo-bar-*.pkg.tar.zst).
- update.sh: copy the db/files by name so repo-add's *.old backups stay
off the medium.
- build-end4-deps.sh: rebuild a local PKGBUILD when it is newer than the
built package (a quickshell _commit bump used to be skipped).
