docs(agents): refine user-edit and test-double rules

Generalize the revert rule to protect any content the user changed or removed, and require confirmation before touching it. Replace the mock ban with a scope rule: checks must not be faked or weakened, and test doubles may replace only what a check does not verify. Sync the matching eval scenario.
