- latest-patch implies check-latest so the newest patch release comes
from the versions manifest instead of a possibly stale runner tool
cache, with a warning when the manifest cannot be reached
- fail fast when latest-patch is combined with a custom download base URL
- never widen an exact toolchain directive pin
- validate go-version-file-behavior on every input path
- widen v-prefixed versions and log when a version is used as written
- document dependency cache invalidation on new patch releases
