Fix: unify --rounds flag and disable profiling when rounds > 1

Remove -n short form for --rounds in run_example.py and scene_test.py
standalone entry to match pytest's conftest.py (which only has --rounds).
Automatically disable --enable-profiling when --rounds > 1 with a warning,
since profiling only captures the first round and multi-round mode is for
benchmarking.
