fix(app): count what the subagents pill's mark is showing

The pill drew the most urgent state of the fan-out next to the size of
the fan-out. Two questions, one pill, 8pt apart: a spinning ring beside
"2 subagents" reads as two agents running when one is. The mark is the
thing the eye lands on, so its state gets read onto whatever number is
next to it.

While anything is happening the pill now names that state and counts the
children in it — "1 running", "2 failed" — and falls back to naming the
total once nothing is. The total is a tap away in the panel, and the
running count is the number worth glancing at anyway.

Label and mark are built by one function so they cannot disagree; the
call site takes both or neither. Every non-done bucket gets copy, not
just the two that are reachable today, because needs_input and attention
become reachable the moment a subagent row carries requiresAttention,
and the failure mode is silently the bug this commit fixes.
