fix(confidence-engine): align empty done and reopen state

- Empty Done immediate transition now sets node.status to resolved
  alongside resolvedNodeIds/doneForNowIds — same canonical parked
  shape as populated Done (no server call required)
- Clarified-question Re-open removes target from doneForNowIds so
  the question visibly returns to Open Questions
- Immediate graph mutation creates new node objects immutably
  (React state semantics), touching only the target node
