deps: Update uucode to v0.2.0 (with unicode 17) (#10895)

This PR updates `uucode` to v0.2.0, with several new Unicode files being
parsed, various fixes (not affecting Ghostty), `wcwidth` grapheme
support, code point iteration, and finally an upgrade to Unicode 17. As
far as this impacting Ghostty, the Unicode 17 upgrade is the biggest
change, and even that is relatively minor.


31655fba3c...v0.2.0

The only needed change to the configuration is to revert `prepend`
characters to being non-zero width for Ghostty. See the comment.

No AI was used except to check the grammar of the comment. AI was used a
bit in the `uucode` changes, but mostly done by hand and closely
reviewed when used.
