ioredis is inoperable in Fresh 2

[ewired]

I am migrating a large Fresh 1 app to Fresh 2 and I am blocked by a guaranteed ETIMEDOUT in ioredis in the vite dev server. https://github.com/ewired/fresh-redis-experiment/tree/ioredis

Task dev vite

ioredis v5 does not support plugging third-party Promise library anymore. Native Promise will be used.

^C

In the same environment, deno run -A test_redis.ts works fine, and ioredis is used without logging the Promise warning or having ETIMEDOUT.
