fn task_status(word: &str) -> Option<ToolCallStatus>Expand description
A task’s own status word, as the frame carrying it draws the call.
The same map a view applies to task_updated.patch.status: the wire
says running where the row says in progress, and stopped is its word
for a graceful cancel, which draws as the kill it is.
An unrecognised word is None. The word arrives here after the call
is finished, so an unreadable word means the task ended without saying
how, and drawing the call as pending again would walk it back down.
