fix: hide completed tasks from priority view immediately

- Priority view is "what to do next" — completed tasks have no place there.
  Always filter them out; removed the "show completed" toggle button.
- Optimistic local hide: when you check a task off inside priority view it
  disappears immediately (no waiting for API round-trip + parent re-render).
  A `locallyDone` Set tracks tasks marked complete in the current session.
