Browser Run: now running on Cloudflare Containers, it’s faster and more scalable

Browser Run migrated from shared Browser Isolation infrastructure to Cloudflare Containers, leveraging Durable Objects for regional pools of pre-warmed browser containers to reduce latency. The state management of containers was migrated from Workers KV to D1 with batched writes via Cloudflare Queues to overcome KV's eventual consistency and throughput limitations, enabling higher scale and faster capacity adjustments. This migration also allows for faster browser image upgrades, enabling features like WebGL and WebMCP.
