v1.3.3

Added

• "Remove from board" action on multi-board articles — when an article exists
  in multiple boards, the dropdown shows per-board removal buttons that detach
  the article from individual boards without affecting forwarded copies

Fixed

• Forwarded article disappears from all boards on delete — deleting a
  multi-board article now only removes the board association, not the article
  itself; forwarded copies in other boards remain visible
• Soft-deleted articles accessible via direct URL — get_article_by_slug!
  now filters out articles with deleted_at set, returning 404 instead of
  showing deleted content
