4.7.0

release: v4.7.0 — deliverables, real viewers & the converge workroom

npm 4.6.0 → 4.7.0.

- Deliverable contract: a task declares required outputs (answer/code/doc/page/
  file); runs pin them as typed output cards, ⚠ on missing. Run modal is now
  timeline(left)/output-cards(right) with REAL per-type viewers — rendered
  markdown, live sandboxed HTML page, colored diff, image preview.
- Converge cockpit: the Goal workroom is a per-run decision panel — review /
  fix(steer) / merge / close each run in one session, expand → the run's output
  cards as the review peek. Group bar: Integrate selected / review / close.
- Fix: closed-task terminal no longer errors (cleanupRun blanks the stale
  worktree/tmux pointers; button guarded).
- Maintenance: reclaim orphaned worktrees (failed/closed run worktrees are disk
  debt ~180MB each) — safe filter never touches running/done work.

e2e 61 checks; typecheck clean; both real viewers and the converge panel
live-verified. /api/runs/:id/file byte serving is path-escape guarded.
