Rework the SQL-schema check so each component is validated against ITS OWN
manifest version instead of a single package-level version applied to every
sql/updates/mysql dir (which mis-flagged independently-versioned sub-extensions).
Add check #11: fail if any update file version exceeds its component manifest
version. This catches migration files drifting onto a different numbering lane
and getting ahead of the release version (e.g. 01.14.00.sql while the manifest
is 01.01.40) at PR time instead of surfacing as a runtime schema mismatch.
