            Automated update of the MIME database from the IANA media types registry,
            Apache mime.types, mime-db gap-fill entries, and curated ManagedCode overrides.

            When MIME data changes, this PR also bumps the package patch version.
            See the workflow summary for the IANA registry date, source counts, and version bump.
