docs(context-layer): replace "committed" badge with git icon (#183)

Swap the small "committed" chip on the two-pillars figure for an inline
Git logo + "git" label so the source-of-truth signal reads at a glance.
Adds GitIcon component matching the existing GitHubIcon/SlackIcon
inline-SVG pattern. Also picks up a Next.js-regenerated next-env.d.ts
routes path.
