The deriver script does "from src import crud" at the top, which only
works when the cwd / sys.path[0] is /app. Running the script by file
path (python /app/src/deriver/deriver.py) puts /app/src/deriver on
sys.path instead, and the import fails with ModuleNotFoundError.
Switch to python -m src.deriver.deriver and explicitly set
WorkingDir=/app so module resolution is deterministic across Podman
versions.
Discovered during the first deploy of the honcho role on lincoln —
honcho-api was healthy on :8000 but the deriver crash-looped 26 times
in two minutes.
