- Remove table header row; entries use rhythm alone, no column labels
- Remove per-row border-bottom; rows breathe without rules
- Update grid columns to 18px/240px/1fr/96px (was 22px/1.1fr/2fr/90px)
- Widen body split to 2.7fr/1fr (was 2.4fr)
- Add 16px top padding to left column
- Replace "This directory" stats sidebar with recent commit log
- Fetch recent_changes in tree handler; add field to TreeTemplate
- Add .tree-log-item/.tree-log-subject/.tree-log-meta CSS for sidebar
