Repository navigation
PR single-commit views now show a GitHub-style commit message box with Prev / Next navigation, Browse files, author/committer details, and a copyable commit SHA. Long commit messages can be expanded and collapsed. Commit titles on a pull request's Commits tab now open the commit within that pull request.
The navigation preserves diff style, whitespace, and outdated-comment settings. The new UI applies to the GitHub themes; other Gitea themes retain their existing behavior.
Compatibility: Gitea 1.27.x and 28.x. Validated on 1.27.3 and 28.1.0 in light/dark themes at desktop and mobile widths.
Upgrading from v0.2.0: extract the package over the existing install, then run gitea manager reload-templates (or restart Gitea). This release updates templates/custom/footer.tmpl, templates/repo/commits_list.tmpl, the generated theme CSS, and its cache key. If you maintain your own overrides of these templates, merge the GitHub-specific changes by hand. No icons or templates were added or removed.
