`TableFooter` ships a corrupted class string

• Where: gem/lib/ruby_ui/table/table_footer.rb:13:
  "border-t bg-muted/50 font-medium[& amp;>tr]:last:border-b-0". The
  amp; is HTML-decoded text pasted into Ruby source; a space before [
  is also missing.
• Effect: every TableFooter emits the tokens font-medium[& and
  amp;>tr]:last:border-b-0 — neither is a Tailwind class, so font-medium
  and the last-row border rule are both lost.
• Fix: "border-t bg-muted/50 font-medium [&>tr]:last:border-b-0";
  re-record (on the 2.0 line) table/*.

Surfaced by the golden HTML suite (PR #536), which pins what 1.6 renders today — this defect included. Per maintainer decision (2026-09-19) main stays as is: this is addressed on the 2.0 line, and the golden snapshot that pins it is re-recorded there with the diff reviewed.

gem/lib/ruby_ui/table/table_footer.rb:13 から始め、TableFooter クラスの文字列を issue で想定されているトークンと照合して調べます。2.0 系列で golden HTML suite を実行し、table/* を再記録して diff を確認します。main を変更せずに、修正されたクラスと確認済みのスナップショットが存在すれば完了です。
