fix(issue-34): merge review - a sub-job cancelled before injection keeps its reason in the review table; unattributed open jobs come with a verdict rule

- registry.get_feedback only returned the detail of the last completed or
  error event, so a sub-job the wrapper cancelled before injection
  (target_not_found, session_busy) reached the review table as a bare
  `cancelled` and its reason was lost (merge review, grok N1). get_feedback
  takes the event kinds to read (default unchanged); the table asks for
  cancelled too and shows NOT-DISPATCHED with the reason. Test T13, both
  reasons, fails without the fix.
- the [귀속되지 않은 열린 잡] line listed jobs registered without
  --parent-job but gave the reviewer no rule for them - the one case the
  table cannot show (claude K1). A rule sentence follows the line whenever
  such a job exists; without one the prompt is unchanged. T6 pins it.
