opencrabs 0.5.3

// Witness for #1621: README.md and src/docs/ shipped a heartbeat subsystem
// the binary never implemented — intervals (`heartbeat.every`, JSON5
// `heartbeat: { every }`), `HEARTBEAT_OK` ack suppression, `ackMaxChars`,
// and config paths under `agents.defaults.*` that the schema does not
// accept. None of it exists. Periodic checks are cron jobs (cron_manage)
// whose prompt reads HEARTBEAT.md; that file is a plain checklist.
//
// This test scans the shipped docs so the phantom claims cannot return.
