watchStuckJobs uses the KEYS command

Hello,

While debugging some performance issues I looked at the watchStuckJobs implementation and saw kue uses the KEYS redis command. Redis recommends that this command should be avoided in production environment due to its complexity (O(n) on the number of keys). https://redis.io/commands/keys

Could you fix this? Or at least stop strongly suggesting using this command? The performance impact is significant with a big enough database.

Regards

Start by locating and reading the watchStuckJobs implementation, then trace how it discovers Redis keys and review the Redis KEYS guidance linked in the issue. Check existing tests around stuck-job watching if present. Done means the implementation no longer strongly recommends or relies on the problematic command and its behavior remains covered by verification.
