refactor: trim redundant test coverage, match stub header convention #6

CleanTool asserted Tool::canSee(fn(Request)) is accepted, but that holds
by closure-param contravariance regardless of whether AuthorizedToSee
is narrowed, so it added no regression signal; BrokenTool in
still_errors.php already guards the real case. Also collapsed 6
near-identical visibility-setter calls in clean.php (all sharing the
same @template bound) down to 2, plus the existing bool-branch case.

Dropped declare(strict_types=1) from the 4 new stub files to match the
existing stub convention (bare <?php) — meaningless in a stub anyway,
since it's never executed.
