OptionalbundleFiles: TemplateBundleFilesthe template bundle's compose documents. Optional for
backward compatibility — when omitted, the three compose-dependent rules
(storage-unconsumed, storage-orphan-volume, storage-env-undeclared)
are skipped. The catalog publish tool always supplies it.
Lint a catalog TemplateManifest. Returns findings — an empty
issuesarray means the template is publishable per the P1 + D8 checks. Never throws for a lint failure; a malformed manifest surfaces as amanifest-invalidissue.
