[Mte90]

If someone want to try :-)

which linters would you like to add?

There's the last clippy issue: module has the same name as its containing module in src/modules/command/mod.rs, and i don't know what's the proper way to rename it.

And then we can add clippy to ci.

I don't know what it was used for #349 and I think that is the case to use the same.

@lxl66566 Let's rename it to cmd.rs
