Fold managed/undo/bisect into the .zit-checkout container v2 (consolidation Task 6)

Sectioned container (ZITCKOT, tagged table, whole-file CRC); payloads are the existing formats unchanged. Byte-1 dispatch migrates legacy checkouts on first write; siblings dead once a container exists. Undo/redo restore and the commit/merge record+membership writes each collapse to one atomic splice. DST gains a legacy-seeded migration sweep (full-legacy or full-container at every crash cut). Registry: the three names move to the legacy tier. Perf on pkgsrc: adjacent update 6.50s (was 6.8), no-op 5.14s (was 7.69); migration of a 66k-file checkout invisible inside one update. check-in: efa29d234f 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
