Project import, dry-run first

scribase import moves a live hosted Postgres project in — schema, data, auth.users and identities, storage objects, and RLS policies — with a resumable state machine so a large import can survive an interruption.

• --dry-run prints the full inventory of what will and will not move before you commit. Run it against a real project on a call.
• User IDs preserved, so existing password logins and JWTs keep working with no forced reset.
• Signing keys are never copied — the importer issues new ones.
• A verification pass proves the import with row counts, checksums, policy parity, and a login proof.
