### Description
A trivial change to make `dev.sh` use -Werror. This is what our CI uses, and it's annoying to have a PR rejected because of a warning that was missed at dev time. Since this is only for `dev.sh`, it won't impact most people's normal workflow.

This also seems to squash a stubborn space leak we see with
subscriptions (linking to canonical #3388 for reference).
This may also fix some of the "Unexpected exception" websockets
exceptions we are now surfacing (see e.g. #4344)
Also: dev.sh: fix hpc reporting
Initial work on this done by Vamshi.
