Complete removal of migration_history system in favor of instance_setting based schema versioning.
Changes:
- Remove migration_history table creation from all LATEST.sql files
- Delete all migration_history model and implementation files (~300 lines)
- Remove FindMigrationHistoryList and UpsertMigrationHistory from Driver interface
- Replace complex backward compatibility functions with simple version check
- Update health check to use instance_setting instead of migration_history
- Simplify checkMinimumUpgradeVersion to detect pre-v0.22 installations
Breaking change:
Users on versions < v0.22.0 (May 2024) must upgrade to v0.25.x first before upgrading to this version.
Clear error message with upgrade instructions will be shown for old installations.
