* fix(runtime): resume children paused for a withdrawn steer
wait_tool pauses every child as soon as a steer is pending, but only a
delivered steer sets steering_active, the flag finish_graph needs before it
resumes them. Removing the steer before delivery left the children parked
and the run waiting on them.
Release the children when deliver finds no input and no steer is in
progress. They stay paused during later model turns of a delivered steer.
* fix(runtime): release children paused by a steer withdrawn mid-turn
The steering_active guard skipped the release whenever another steer was
being handled. A child started during that turn is outside its
interrupted_children snapshot, so nothing resumed it after a second steer
was withdrawn and finish_graph waited forever.
Release every child a delivered steer does not hold. Each deliver re-takes
that snapshot, so a paused child outside it can only belong to a withdrawn
steer.
* fix(runtime): keep a replacement reusing a call ID out of the held steer
interrupted_children stores call IDs, and child() can replace a closed gate under the same ID. The replacement then looked held by an earlier delivered steer, so a withdrawn steer left it paused forever in a replaced turn. Drop the ID when its gate is replaced.
wait_tool reused the name gate for its pause loop, so every parallel task
returned the last child's result id and its done callback closed that
child's gate. The message reducer then dropped all but one pending result,
and the model was told that a running subagent had been interrupted.
Rename the loop variable so each call keeps its own gate.
* feat(runtime): add Queue and Steer for active Web runs
* style(frontend): format Queue and Steer controls
* fix(runtime): retain user Steer controls and order active inputs
* docs: add Chinese changelog entry for Queue and Steer
