Describe the Bug

When using 2 wrangler in localhost mode:
aka
wrangler dev -c worker1/wrangler.jsonc -c worker2/wrangler.jsonc

then Wrangler only passes the Hyperdrive env vars to the primary worker, but not to secondaries - if the secondary has his own hyperdrive config, it just does not work. Making RPC development in localhost mode extremely painful.

you see that the hyperdrive string is wrong - compared to run it seperately.

Please provide any relevant error logs
