repocache: persist the content log's scan index

The lazy content channel re-walked every frame header on each open — O(store) before the first byte of any comment, cat, or annotate. The scan's product (entries, hash index, shun rows, config cursor, tail key) now persists as .zit-cache/index, self-validating and LogKey-keyed: an exact tail adopts whole, a grown log resumes the walk over the tail alone, and anything else falls back to the authoritative scan (--no-cache never consults it). pkgsrc: info 1.7s -> 0.44s, timeline -n 5 4.3s -> 0.96s. check-in: f2bfd36e74 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
