/**
 * #1577 — `security.injection_blocking` is a first-class config key.
 *
 * The gsd-read-injection-scanner hook reads `.planning/config.json`
 * `security.injection_blocking` to decide whether a HIGH detection blocks
 * (opt-in) vs. stays advisory (default). Before this, the key was unregistered:
 * `isValidConfigKey` returned false and `gsd config-set security.injection_blocking`
 * was rejected as "Unknown config key" — the knob was settable only by hand-editing
 * config.json. These tests lock the registration + the nested write shape the hook
 * reads, and the advisory-by-default contract.
