This pull request optimizes code diff highlighting in the PR Files Changed view, which is a major CPU bottleneck and hot path in production. Previously, Gitea executed the expensive `DiffMatchPatch` algorithm twice for every matching deleted/added line pair (once for the deleted line, and once for the added line). We now run the diff algorithm once and cache the resulting `DiffInline` on the `DiffLine` struct itself, allowing the second line to render via a 0-cost cache lookup. --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com> Co-authored-by: silverwind <me@silverwind.io>
