/**
 * Degenerate-loop breaker for fabric_exec. Identical calls back-to-back are
 * how lower-tier models burn a session (2026-09-15: 220x `bash echo noop` on
 * glm-5.3-flash). The fingerprint is the code plus the payload values, since
 * a wrapper such as `pi.bash({ cmd: π.cmd })` carries its work in payloads.
 * Payload key order and display names do not count. Any differing
 * fingerprint resets the count.
