- 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.
