/**
* Issue #2357 - Redis is optional. When `REDIS_URL` is unset, the rate
* limiter must use the in-memory store instead of probing localhost.
*
* `ioredis` has a packaging quirk (`@ioredis/commands/built/commands.json`
* is actually JS, not JSON) that prevents `node:test` from importing it
* cleanly, so we verify the contract at the source level instead.
