Code Review
This pull request is a large refactoring to rename the GEPA feature to Prompt Optimization. The changes are extensive, touching many files across the backend, API client, and frontend. Overall, the renaming seems consistent. However, I've found a critical issue where an old job type enum is still being used, which will likely cause status updates for prompt optimization jobs to fail. I've also noted a change in error handling that seems to be a regression. Please see my detailed comments.

🧹 Nitpick comments (1)
app/desktop/studio_server/prompt_optimization_job_api.py (1)
625-639: Comment about exception swallowing is slightly misleading.The comment at line 631 says "this swallows the exceptions from each call", but
asyncio.gatherwithoutreturn_exceptions=Truedoes not swallow exceptions — it propagates the first one. Exceptions are actually swallowed insideupdate_prompt_optimization_job_and_create_artifactsitself (lines 330-333). The comment should either be moved/reworded, orreturn_exceptions=Trueshould be added to match the stated intent.Note that
update_prompt_optimization_job_and_create_artifactscan raiseHTTPExceptionfrom lines 293-295 (before the try block), which would propagate throughgatherand cancel sibling tasks. This is a pre-existing concern, not introduced by this PR.
