[Kyle-Ye]

Summary

• Complete preference bridging, reuse notifications, and teardown cleanup in ViewGraph.
• Implement safe-area measurement and alignment, rebuild graphs when requested outputs change, and return transformed display lists.
• Preserve nested graph contexts and scheduling edge cases, with regression coverage for lifecycle, layout, and update requests.
