Feature Request: `f` Binding to run `cargo clippy --fix --allow-dirty`

## Proposal

Would it be possible to introduce a new default keybind `f` when running `clippy` mode to apply Clippy autofixes via `cargo clippy --fix --allow-dirty`?

Sidenote, absolutely love `bacon` :)

Start by locating the clippy mode keybinding definitions and the command execution path in bacon. Check how existing mode actions are registered and tested, then verify that pressing f runs `cargo clippy --fix --allow-dirty` only in clippy mode and that the command completes as expected.
