mika kuns 29ea18c427 fix(ui): make diff-stat parsing locale-safe and dedupe the two parsers
TaskRowViewModel had its own ParseDiffStat expecting "+12"/"-3" tokens that
`git diff --stat` never emits, so the row badge always showed 0/0. Meanwhile
DetailsIslandViewModel's parser matched only the English words
"insertion"/"deletion", so it broke on a localized git (e.g. German Windows:
"Einfügung(en)"/"Löschung(en)").

Row and detail badge now share one parser, anchored on git's untranslated
(+)/(-) suffix instead of the language-dependent word before it, so it reads
correctly in any locale. Also corrected the Worker CLAUDE.md's branch-name
claim (`claudedo/{taskId[:8]}`) to match the actual full-GUID branch name.
