This PR updates artifact upload/download and metadata lookup behavior:
upload_artifactnow returns the uploaded artifact ID instead of storing it automatically in trial user attrs.set_user_attrso callers can explicitly persist artifact IDs when desired.get_all_artifact_meta(study)now handles multi-trial studies with uneven or missing artifacts.get_all_artifact_meta(study, trial)now supports JuliaTrials and raw Python Optuna trial objects.download_artifactnow writes to the exact requested file path.Regression tests were added for returned artifact IDs, explicit user attrs, mixed artifact counts across trials, Python/Julia trial metadata lookup, and exact download paths.
