Add /json Endpoint to Bun Inspector Server to Support External Debugging Tools

[june07]

What is the problem this feature would solve?

Currently debugging with Chromium DevTools is possible but a manual copy paste of the debug socket is needed as you can see from the first screenshot where I copy/pasted "localhost:4000/7u1bqmpvhg" into DevTools. https://github.com/june07/nim is a tool I wrote for Node.js (works for Deno as well) some years back for this and it would be nice to use it for Bun as well, to streamline things.

Node/Deno both implement inspect servers that have a json endpoint which contains data about the debug websocket:

For example, http://localhost:9229/json will display this output which allows local clients to determine the debugger web socket details so as to connect: ws=localhost:9229/abcdbdb5-f00c-4554-88e5-d740ba881234"

I'm sure those reading this are familar with this in Node... but in case not: https://nodejs.org/en/learn/getting-started/debugging

What is the feature you are proposing to solve the problem?

Implement the same inspector sever /json endpoint
