`strictly`::
Any version not matched by this version notation will be excluded.
This is the strongest version declaration.
On a declared dependency, a `strictly` can downgrade a version.
When on a transitive dependency, it will cause dependency resolution to fail if no version acceptable by this clause can be selected.
