Stop card testing and bot checkouts at payment. Clean up the fake customers bots leave behind.

Linesman stops bot checkouts and card testing at the payment step, then finds and deletes the fake customer accounts bots leave behind. You start in Watch mode: it records what it would block and checks it against your real orders first. The checkout guard covers Shop Pay and express checkout, returning customers always pass, and Attack mode tightens checks during an attack. Delete bot customers after a backup and suppress them in Klaviyo. No redirects, block pages or theme code edits.
