feat: add pretend support to runSeed

Pass pretend through MigrationService.seed() and QBMigrationManager.runSeed().
When pretend is true, the QueryBuilder is set to pretend mode so no SQL executes.
The query is now passed as a second argument to postProcessHook so callers
can read the query log to display what would have been run.
