Subject: [PATCH] chore(deps): hold unicode-width below 0.2.3 so ratatui keeps
 sound marks one cell wide
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ratatui-core 0.1.2 adds a cell to each halfwidth katakana sound mark
(U+FF9E, U+FF9F) because unicode-width used to count them as zero-width.
unicode-width 0.2.3 counts them as one cell itself, so with both,
ratatui lays "ｶﾞ" out over three cells while terminals draw it in two,
which fails the buffer_rows test on every platform in #711.

Bound unicode-width below 0.2.3 so cargo update and lock file
maintenance stay on 0.2.2, and hold Renovate to the same bound, since
Renovate otherwise widens the range to admit 0.2.3.
