fix: parse VALKEY_URL into RedisOptions object for BullMQ connection

Browse Source 
BullMQ v5 RedisConnection constructor does:
  Object.assign({ port: 6379, host: '127.0.0.1' }, opts)

When opts is a URL string (via 'as unknown as ConnectionOptions'),
Object.assign only copies character-index properties from the string,
so the default port 6379 was never overridden — causing ECONNREFUSED
against the wrong port instead of the configured 6380.

Fix: parse VALKEY_URL with new URL() and return a plain RedisOptions
object { host, port, ... } so Object.assign merges it correctly.
