- tests: use https in the OTLP endpoint fixture to clear the S5332 "http protocol is insecure" security hotspot (quality gate: new_security_hotspots_reviewed). - cli: add the "tracing disabled" else branch in _init_worker_observability so the worker logs parity with app.py when no OTLP endpoint is set. - cli: trim the verbose inline comment in worker() (the WHY lives in the helper docstring), per review.
