Type the #13700 seed fixture as any: keep the metadata-protocol DEBT ledger at its frozen 63

The three new makeStubEngine([legacyReferenceToRow]) call sites each raised
TS2322 under the debt instrument (the parameter intersection collapses
metadata to string, while stored-seam seeds deliberately carry object-literal
metadata that the stub stringifies). Annotating the fixture const `any` — the
file's established stub spelling — removes exactly the 3 new errors; the 7
pre-existing frozen errors in this file are untouched, so the package measures
63 again, matching the ledger. No behavior or assertion change; suite 9/9.
