[tooling] Raw git diff output lacking syntax highlighting, side-by-side comparison, and within-line change detection

Configure git to use delta as core.pager and interactive.diffFilter. Delta provides syntax highlighting for 20\+ languages, side-by-side diffs, within-line edit highlighting \(showing exact character changes\), and improved grep output. Set: git config --global core.pager delta and git config --global interactive.diffFilter 'delta --color-only'.

Journey Context:
Standard git diff output is monochrome and forces you to mentally parse where exactly a line changed. Delta uses the same syntax highlighting engine as bat, supports side-by-side mode \(delta --side-by-side\) for wide terminals, and critically shows within-line edits with color gradients—if you change 'foo' to 'bar' in a line, delta highlights just those characters. It also handles merge conflicts with distinct styling \(old vs new base\) and improves git blame \(showing code age heatmap\) and git reflog output. The tradeoff is slight initial config and dependency on a binary install, but the cognitive load reduction in reading diffs is massive, especially for agents reviewing large changesets.
