test(frozen-pin): an added or removed file, and listing order, pinned by tests; drift named apart from missing

Browse source 
K5 survived a full run (a mutant ignoring an extra or removed file left the suite green) and K4
(sort removed) was caught only by corpus data. Now pinned with no corpus: the add arm, the remove
arm, and a shuffled directory listing digesting the same. The gate says "pin-drift" for a drifted
copy instead of "artefakter mangler"; the unread "store" key is gone from frozen_bundles.json; the
forbidden-path scan covers md/yaml/yml/toml and proves a known positive per suffix.

Five mutants killed in a scratch clone (drop-last-entry 8 failed, no-sort, no-names, drift-as-missing,
scan-suffixes-narrowed 1 failed each).
