scripts/container_sweep_single.sh: clone pristine OpenClaw state to
/tmp/ per sweep before starting the gateway. Carries over config
(openclaw.json, identity/, devices/, exec-approvals.json, tasks/,
subagents/, flows/, cron/) but leaves runtime dirs (agents/,
workspace*/, logs/, memory/, cache/) empty. Sets OPENCLAW_STATE_DIR
to the isolated dir so the gateway writes to /tmp instead of the
shared host mount. Fixes the cascading "RPC agents.create timed out
after 60s" failures caused by 4k+ stale agents accumulating across
sequential sweeps.
profiles/frontier_qwen_3_6.yaml: fix base_model from
openrouter/qwen/qwen-3.6-plus (with dash) to openrouter/qwen/qwen3.6-plus
(no dash). The dashed slug is unknown to OpenRouter and silently fails;
the no-dash version is the real canonical.
