Improves Visual History rendering

 - Replaces the charting dependency with a canvas-backed timeline for smoother dense-history rendering and more control over interactions
 - Adds richer hover, zoom, scroll, brush, slider scrub, and slice filtering behavior so exploring busy histories feels more responsive
 - Shows author avatars, current-user naming, accessible commit text, and configurable additions/deletions colors
 - Keeps editor scope more stable when diff tabs open and avoids churn from interim slider selections
 - Removes the unused billboard dependency and adds tests for timeline data packing, binning, layout, and hit testing
