What changes are included in this PR?
SQL catalog schema detection now probes the V1-only column directly, and V0-to-V1 migration tolerates a competing catalog instance completing the same migration first. A failed DDL is accepted only after re-detection confirms that V1 is installed.
This change was extracted from #2773 so the Unknown-type work can be reviewed independently.
