Usage:
  scripts/tea_comment.sh <issue_or_pr_index> <body_file|-> [repo]

Examples:
  scripts/tea_comment.sh 374 /tmp/comment.md
  cat /tmp/comment.md | scripts/tea_comment.sh 374 - jihoson/The-Ouroboros

Notes:
  - Use file/stdin input to preserve real newlines.
  - Passing inline strings with "\n" is intentionally avoided by this helper.
