[request] Recursive option for `readDir()`

Is there a chance `fs.readDir()` gets a `recursive` option?

The documentation shows how to implement your own recursive version. It works but it gets very slow very quickly because there's a frontend-backend-roundtrip for every folder that gets read.

I've implemented the same thing in Rust and transfer all paths in one go back to the frontend. It's a lot faster but it seems it still blocks the main thread. Then I've tried to add threads with the help of AI but that's where I've realized I really need to know Rust in order to implement that properly, which unfortunately I don't.

That's why I think a `recursive` option would be really beneficial.
