Research direction
Start by reproducing the delay with rust-analyzer enabled while editing an exercise, then trace how rustlings detects file changes and runs checks across the exercises folder. Done means an edit does not trigger unnecessary checks for every exercise and commands such as h, n, l, and q remain responsive.

Description
Description
This is the video that the issue happens:
https://github.com/user-attachments/assets/00adc400-8e44-4899-9646-a7cff18bd7aa
It can be shown that every time I update the code of an exercise, the rust-analyzer builds the whole exercises folder (it has like 156 exercises and the extension run the code check for every single of them). During this process, I cannot use any command (h, n, l or q). Only after it finishes, rustlings tells me if my solution is correct or not and directs me to the next exercise.
I don't think it's a bug, but rather a code design issue. If I turn of rust-analyzer, it seems the issue's gone but I still have to wait for like 1-2 seconds for rustlings to detect file changes.
Please look into this issue and fix it. Thanks!
