Consider new lints for inclusion simple_directive_paths

PREFER simple directive paths.

Using simple directive paths (avoiding redundant ./ or backtracking ../ segments) makes the code cleaner, more consistent, and easier to read. It also reduces the risk of confusion when resolving paths relative to the source file.

BAD:

import '../src/bar.dart';

GOOD:

import 'bar.dart';

I'm in favor of putting this in recommended. I think it's low impact, but it will probably be helpful on occasion and shouldn't ever be harmful.

Decision: recommended
