Fix: child tasks only from spec/breakdown agents; live review badge

Two fixes from real usage:
- Child-task creation is now gated to story-producing skills (spec-writing,
  story-breakdown). A code/design/test agent's output is the artifact — a numbered list
  in it (e.g. file names from an engineer) is no longer mistaken for child stories.
- The review-inbox badge now updates without a refresh: it polls more often (6s),
  refetches on window focus, and reacts to a REVIEWS_CHANGED event the board fires after
  Run (with a couple of delayed pulses to catch the ~5s completion) and the review page
  fires after approve / send back.
