- mysql_dump_grants(): backs up user grants via SHOW CREATE USER + SHOW GRANTS,
skipping system users (root, mysql.sys, etc.)
- mysql_restore_databases(): restores .sql.gz dumps and grants.sql from snapshot
- Backup flow: grants dumped alongside database dumps into _mysql/
- Restore flow: automatically restores MySQL databases and grants when _mysql/
exists in snapshot and target has MySQL enabled
- CLI: --skip-mysql flag to opt out of MySQL restore
