forbidReachable

Forbids modules matching from from transitively depending on modules matching to - the indirect counterpart to forbid { }, which only checks direct edges. Follows the full production dependency closure, so a banned module reached through any chain is a violation. Reports forbidden-transitive-dependency at severity (default ERROR).
