Meta Vens 66bd07b941 Pin the legacy-layout and missing-header refusals
The legacy catalog layout reaches CultMesh's fallback reader, and a nil header
was the only defaulted header; each gets one vector or test. The C# store
tests catch the refusal where the store attaches.

"""Generates the shared C0 refusal vectors from the pre-Cut 2 v1 store (written before any
variant code existed). Every runtime's tests read the committed bytes; nothing regenerates them
at test time. Run: python generate.py (needs msgpack).

extra-slot-full-payload.msgpack v1 header, record item:anvil gains slot 4, payload stays full
legacy-catalog-extra-slot.msgpack
v1 header, catalog entry in the older layout (contentHash at slot
5), so CultMesh's legacy snapshot reader takes it, plus the
extra-slot record
