MariaDB rejects 34149345 for VerifiedBuild when the column is MEDIUMINT
(signed max 8388607), as in old 8.x schema migrations. Replace corrupt
value with 0 in archive and base dumps.
Add data/sql/tools/clamp_verifiedbuild_mediumint.py to re-scan archive,
updates, and base INSERT/UPDATE blocks that list VerifiedBuild.
