Announcing wrangler dev — the Edge on localhost

Introduced `wrangler dev` as a GA feature, providing an edge-based development environment for Cloudflare Workers. This enables live reloading of code pushed to the edge, direct terminal access to `console.log` output, and the ability to test edge-specific features like Cache API and KV namespaces in a development-specific environment without affecting production data. This enhances the developer experience by offering a high-fidelity, consistent testing environment that mirrors production without the complexity of local environment replication.
