InitBoy e19bec1422 fix(task-tool): cancel and schedule deferred cleanup on polling safety timeout (#3097 )

When the poll loop's safety-net timeout fires (poll_count > max_poll_count),
the background subagent task was abandoned without cancellation or cleanup,
leaving a stale entry in _background_tasks indefinitely.

The original code had a comment promising "the cleanup will happen when the
executor completes", but run_task() in executor.py never calls
cleanup_background_task after reaching a terminal state -- the promise was
never implemented.

This change mirrors the asyncio.CancelledError path: signal cooperative
cancellation via request_cancel_background_task and schedule
_deferred_cleanup_subagent_task to remove the entry once the background
thread reaches a terminal state.

Direct cleanup at poll-timeout time would introduce a race: run_task() could
remove the entry while the poll loop is still mid-iteration, causing a
spurious "Task disappeared" error. The deferred approach avoids this by
waiting for terminal state before removal.
