Inspired by treefmt-nix's `config.build.check` option, add a similar check function to `treefmt.withConfig`'s wrapper. `check` is a function of `Path → Derivation`, which returns a derivation that builds ok when the path is already formatted, or fails to build if the wrapped-treefmt would change the path's formatting. Add the `check` function, tests for it, and initial docs. See treefmt-nix: https://github.com/numtide/treefmt-nix/blob/db947814/module-options.nix#L301-L349
