Clean-room README test found a newcomer hits failures in the first 5 min —
all doc/script, not sim bugs. Fixes:
- scripts/run.sh: use ./.venv/bin/python (was bare `python` → ModuleNotFoundError:
uvicorn unless the venv was activated; now matches sandbox-up.sh).
- NEW `aci-sim query CLASS [--dn/--host/--json]`: stdlib aaaLogin→cookie→query
helper so newcomers don't hand-roll auth cookies (the old README smoke test
`curl class/fabricNode.json` had no auth → returned an APIC error envelope).
- README: 60-second quickstart + embedded topology screenshot (docs/images/
topology.png), port-mode leads with `aci-sim run`, smoke test uses `aci-sim
query`, install notes git+https is package-only.
900 tests pass (+12 for aci-sim query).
