Replaces the plain activity dot on the context panel rail's Git button with a numeric badge of the changed-files count from the git store status, so the count is visible at a glance without opening the Git surface. Large counts cap at 99+ to keep the pill within the 36px button. The badge is reflected in the button's accessible label and the hover tooltip. Fixes #2364
