Improving request debugging in Cloudflare Workers

What this post added

Introduced a Network panel to the Cloudflare Workers inspector, mirroring Chrome DevTools' functionality. This panel allows developers to inspect request and response headers, raw responses, timings, and initiators for requests made by Workers to origins. It also supports exporting subrequests as HAR files. The implementation involved integrating with the DevTools Protocol, parsing JSON-RPC messages, and adapting the frontend to store response bodies on the client side to manage backend memory.
