The checker reads each package's tag prefix, changelog and assemblies directory
from scripts/release-packages.mjs and derives the release record from git tags.
A first release is the absence of any older tag in a checkout that holds other
tags; a malformed same-prefix tag, a checkout without tags and an unreadable
repository refuse. The measured set is every managed assembly (CLI header in
the PE bytes) tracked at the previous tag at any depth; an unbuilt one is a
break, a built assembly with no namesake is an addition.
Deleted with their branches, refusals and tests: --first-release, --api-new,
--tag-prefix, --changelog, --api-baseline-path and the workflow first-release
decision line. Any unknown option is now a usage error.
