Raxol.Journal.Test.MutationAnchor (Raxol Journal v2.8.0)

The anchor check of a mutation-control checklist: the line a control tells a reader to mutate must still exist verbatim in the source.

For ExUnit suites: a missing anchor fails the calling test.

Summary

Fail unless the file at path still contains fragment. mutation and must_fail are the control's own text, repeated in the failure message.
