* chore(ai-workflow): track repo-managed review tooling

* fix(ai-workflow): remove repo-specific path assumptions

Make shared workflow hooks and APK testing guidance resolve paths from the repo and contributor environment so the tooling works for all contributors, not just one machine.

Conditional Module Loading HIGH loads large data only when needed bundle, conditional-loading, lazy-loading

Conditional Module Loading

Load large data or modules only when a feature is activated.

Example (lazy-load animation frames):

function AnimationPlayer({ enabled, setEnabled }: { enabled: boolean; setEnabled: React.Dispatch<React.SetStateAction<boolean>> }) {
  const [frames, setFrames] = useState<Frame[] | null>(null)

  useEffect(() => {
    if (enabled && !frames && typeof window !== 'undefined') {
      import('./animation-frames.js')
        .then(mod => setFrames(mod.frames))
        .catch(() => setEnabled(false))
    }
  }, [enabled, frames, setEnabled])

  if (!frames) return <Skeleton />
  return <Canvas frames={frames} />
}

The typeof window !== 'undefined' check prevents bundling this module for SSR, optimizing server bundle size and build speed.
