Overview

Survivor-rerun fast path for Runner.

When --survivors-from is given, this collaborator loads the prior report and either:

* builds stub Mutants directly from +activation-recipes.json+ (the recipe
  fast path, bypassing source parsing and mutant generation), or
* filters a freshly generated mutant list down to the prior survivors.

In both cases it records #survivor_stats (matched/unmatched counts and the drift warning) for the Runner to attach to its Result.
