Is your feature request related to a problem? Please describe.

I tend to press "reformat" a lot out of habit and sometimes I've written a line where I create a new variable but haven't used it yet. ruff --fix removes that variable (rule F841):

x = fun()

gets turned into

fun()

Describe the solution you'd like

I would like to disable the rule responsible for this (F841), but keep it on the cli where I want to run ruff via pre-commit which should remove any unused code/variables. E.g. by running it via ruff check --fix --unfixable F841.

Describe alternatives you've considered

Not running ruff on reformat. Add another config in the project which has these rules disabled and configure this in the editor config.
