add --comments flag to issue/pr view; show reply threading

- issue view and pr view now show only a comment count by default
- pass --comments to include the full thread
- JSON output always includes comment_count; comments array only with --comments
- each comment in the thread includes reply_to (null for top-level, parent
  comment id for replies)
- human-readable view shows a dim '↳ reply to <short-id>' line on replies
