API:
- WorkstreamWithTaskCounts schema extends WorkstreamRead with
tasks_total/todo/in_progress/blocked/done fields
- /state/summary now includes these counts in open_workstreams via
a single extra GROUP BY query (workstream_id, status)
Dashboard:
- Replace domain workstream-count bar with a horizontal stacked
progress bar per workstream (done/in-progress/blocked/todo)
- Workstreams with no tasks show "no tasks yet" annotation
- Workstreams with tasks show "X/N done" label after the bar
- Sorted by domain then title so domains group naturally
