Port bun-mariadb schema guard, targetId fix, lazy init and tests

- schema: add --dry-run (sync in a rolled-back transaction) and require
  confirmation (or --yes) before dropping tables or columns; unapproved
  destructive changes are refused
- only rebuild tables whose CREATE TABLE statement changed
- always AND targetId with the query, regardless of searchOperator
- empty IN / NOT IN lists become 1 = 0 / 1 = 1
- initialize lazily on first call so importing never throws
- read CLI version from package.json, chmod CLI on compile, pin @types/bun
- add SQL generator, value and schema guard tests

+Only tables whose definition changed are rebuilt. Changes that discard data (dropping a table, or a column removed from the schema) are listed and need confirmation before they run. Non-interactive runs (CI, scripts) refuse them unless `--yes` is passed. The plan is exact: `--dry-run` runs the whole sync in a transaction and rolls it back.
