Blazing fast development with full-stack frameworks and Cloudflare

Introduced `getPlatformProxy()` API and Miniflare's magic proxy to bridge Node.js and workerd runtimes, enabling framework dev servers to access Cloudflare's platform features (D1, R2, KV) locally. Updated framework adapters and plugins to utilize this API. Enhanced `wrangler pages dev` and `wrangler pages build` to support full-stack frameworks. Introduced `npm run dev` shortcut for framework dev servers. Improved `wrangler.toml` configuration for bound resources in Pages. Added `npm run build-cf-types` for TypeScript integration.
