The Performance Tests job collected 26 items then aborted with
`ModuleNotFoundError: No module named 'src'` on test_frame_budget.py,
which does `from src.core.csi_processor import CSIProcessor`. The bare
`pytest` console script does not put the cwd (archive/v1) on sys.path;
`python -m pytest` does. pytest aborts the whole session on a collection
error, so this one import masked the entire (otherwise mock-based,
self-contained) perf suite.
Verified locally: bare-script path reproduces the exact error; `-m`
resolves it and test_frame_budget.py passes 3/3. The other two files
(test_api_throughput.py mock server, test_inference_speed.py MockPoseModel
+psutil) are fully self-contained — no test hits the running server.
Closes the last red job in the v1-API CI chain (#910/#911/#913).
