key_help, selector and control each carried their own East Asian width and truncation logic with slightly different rules, and cli clipped tmux labels by code point, so a CJK display name ran twice as wide as an ASCII one before its ellipsis appeared. Move the cell-width helpers into herdr_hub.text, make truncate_label cell-aware, and sanitise control characters before curses draws a row so an escape sequence in a remote error cannot be rendered as ^[ and misalign the list.
