Emergency Kestrel Fix

[rajeee]

Fixes # .

Pull Request Description

Ideally, this should have been done in #480, but we missed it. #480 works for buildstock_local, but in HPC, the project directory cannot be referenced from the user's home directory - it needs to be copied over to the local scarth. This PR adds the necessary copying so that BSB can work in Kestrel.

If you've tested this now works in HPC, then I approve.
