chore(nix): add mold linker to shell.nix to improve linking speeds.

[lockedmutex]

Description: I added mold to required dependencies and set mold as the default linker while compiling the application, in shell.nix

@Lab-8916100448256 @jetcookies Can you test if you can compile the application and run it in the nix-shell/nix develop?

For some reasons I have this error :

     Running `target/debug/picoforge`
target/debug/picoforge: error while loading shared libraries: libudev.so.1: cannot open shared object file: No such file or directory

modifying shell.nix like below is fixing that :

diff --git a/shell.nix b/shell.nix
index 123579d..d9d961e 100644

@Lab-8916100448256 added udev check again

I'm AFK for lunch. Will test when I come back home

Works fine now.
