Is there also a way to specify files to ignore in air.toml? This would be useful for other packages that automatically create files, such as extendr, savvy, Rcpp (I guess).

I think there is a general consensus to ignore files with keywords like @generated.

So that the Cargo.lock files also contain it.

@etiennebacher not yet but we will likely have an exclude field in the toml that will let you do that. It will get combined with the default excludes
