.tree-row and .tree-total leave the stylesheet #4641

The .tree-row and .tree-total rules are gone from the stylesheet and from the design doc. Since #4203, the repository tree listing draws its rows and its total line with §5's .row, .row-trail and .card-foot, so nothing used these four rules any more.

• src/web/style/content.ts: the four rules for .tree-row and .tree-total are deleted.
• docs/DESIGN.md: both names are removed from the style/content.ts class list in §5d.
• docs/design/baseline.json: not changed. It is already empty, so there is no count to lower.
• test/tree-listing.test.ts: not changed. It already asserts that the tree page's markup contains neither name, which is the form the issue allows. Because of that, grep -rn under test/ still finds both names on that test's two absence assertions; under src/ it finds nothing.

The tree page should render the same as before, since only rules that no markup matched were removed. I did not check it in a browser. test/tree-listing.test.ts still passes, so the tree listing's rows, links, sizes and total are all still there.

bun scripts/design-lint.ts is clean, and bun test passes on test/design-lint.test.ts, test/tree-listing.test.ts and the other design tests (design-audit, design-map, og-designs, review-design).

To try it: open any repository's tree in the preview, for example /<owner>/<repo>/tree/main/src.

main has been merged in. The one conflict was that same §5d line in docs/DESIGN.md, because main had meanwhile dropped the .explore-* names from it. The resolution keeps main's line with .tree-row and .tree-total also removed. Against main, the diff is still just these two files (1 insertion, 5 deletions).

The tree page should render the same as before, since only rules that no markup matched were removed. I did not check it in a browser.

bun scripts/design-lint.ts is clean after the merge. bun test passes on test/design-lint.test.ts, test/tree-listing.test.ts, test/design-audit.test.ts and test/design-map.test.ts.
