Generated files carried the RelSpec version and build date, so every rebuild produced a diff even when the schema was unchanged. - bun, gorm, drizzle: remove the GeneratedBy template field and line - pgsql, mssql, sqlite: emit a constant "-- Generated by RelSpec" - bun: replace the version header test with a version-free assertion pkg/buildinfo is unchanged and still backs the CLI version.
