Subject: [PATCH] studio: pin peft to 0.18.1 to fix export subprocess issues
 (#5015)

* studio: pin peft to 0.18.1 to fix export subprocess issues

peft 0.19.0 causes export subprocess shutdown failures in Studio.
Reverting to 0.18.1 resolves the issue.

* studio: move peft pin to extras-no-deps to prevent torch upgrade

Installing peft via overrides.txt would resolve its deps and pull in
torch>=0.11.0, breaking other pinned packages. Moving the pin to
extras-no-deps.txt ensures --no-deps is used during install.
