## lsphp-repo-version.sh PHPVER [ARCH] — print the newest lsphpPHPVER package
## version in LiteSpeed's noble apt index for ARCH (amd64 | arm64; default
## $LSPHP_ARCH, else amd64, so callers that pass nothing behave as before).
## The awk/sort pipeline is byte-for-byte the one that used to be inlined in
## build-push.yaml and lsphp-source-emergency.yaml.
## Test hook: LSPHP_INDEX_FILE=<path> reads that Packages file instead of curl.
## Exit 1 (message on stderr) if the arch is unknown or the package is absent.
