test(acp): update commands list snapshot for steer + queue

acp_adapter/server.py:_ADVERTISED_COMMANDS now includes "steer" (inject
guidance into active turn) and "queue" (run prompt after current turn
finishes) between "compact" and "version". Production code is the source
of truth; this test was the last reader still on the pre-feature snapshot.

The substantive features were added in PRs that introduced steer/queue
themselves; this is purely test-snapshot follow-through.
