Sub-manifest: accept in the S-card writer what the parser accepts

The S hash is validated case-insensitively and kept raw, so a parsed card carries whatever spelling it was given. The writer asserted the narrower lower-case spelling, so re-emitting a card the parser had just accepted tripped the assertion. It now asserts the parser's own predicate.

Reachable only once something emits, which nothing does yet; found by round-tripping an upper-case hash through create. check-in: 6e64c8976c user: dmestas tags: sub-manifest

Sub-manifest: card alphabet, artifact type, and the specification's vectors

Adds S as the twenty-second card letter and SUBMANIFEST as the ninth artifact type, per draft-fossil-submanifests-00 sections 3 and 4. Type determination reassigns after the card scan rather than during it, so no type is committed while cards are still being read (section 9.1). Reading and classification only: no tree walk, no emission.

The draft's seven appendix vectors ship alongside, each named by the SHA3-256 the draft states and checked by a test that recomputes it. check-in: 9b8bad477a user: dmestas tags: sub-manifest
