Make Directory Name More Unique

[michaelmckinsey1]

• Addresses Unique naming for torchrun directories #59 by adding the first 8 characters of the UUID to the folder name. Since this stems from jobs running on different processes, this will never conflict in the case of simultaneous jobs.

Previous name:  torchrun_hpc-scaffold_2026-01-29_10h57m26s
New name:       torchrun_hpc-scaffold_2026-01-29_10h57m26s_79ad38c7

@michaelmckinsey1 This will still be problematic and asks for the time twice. Instead, what about adding a unique suffix of _{id}?

This is fine with me. Is the updated solution agreeable?
