v1.0.0: add char-width and search-highlight to cl-tty library

char-width → cl-tty.box (text.lisp): terminal column width for Unicode
  characters including CJK, emoji, combining marks, and tab.

search-highlight → cl-tty.markdown: wraps query matches in **bold**
  markers for search result emphasis. Pure function, zero dependencies.
