P2 "Review-first interactive UI" ✅ for diffnav may be overstated

diffnav is consistently described — by its own README and third-party listings — as a git diff pager built on top of delta, not a dedicated review-first tool. delta received ❌ for this row, yet the two tools share the same underlying renderer. The meaningful differentiator for diffnav over delta is the file-tree sidebar, which is captured separately in the "Multi-file review stream + sidebar" row. Worth double-checking whether the ✅ here is intentional or whether ❌ (matching delta) better fits the table's intended distinction between pager-style tools and interactive review UIs.
