Levi Neuwirth 437e0758a0 Phase B follow-up: real acceleration-snapshot path + base role bound 
Review findings on 794400c. The criterion-4 harness stored current
(v2) Score bytes stamped V0 in the canonical_base slot and decoded
them with the unversioned decoder — bypassing the schema-major
snapshot contract Phase B built, and misusing the base role. Fixed
substantively: the harness stages a properly-roled ACCELERATION
snapshot (ChunkKind::Snapshot stamped for_major(2), referenced from
Manifest::acceleration_snapshots) and decodes through
Score::decode_canonical_versioned keyed by the stamped major — the
versioned seam now exercised end-to-end through the bundle, giving
the snapshot role its first real producer/consumer.

Consequences: max_supported_major(Snapshot) -> 2; and since the
per-kind gate no longer implies it, the canonical-base-stays-major-0
rule is enforced per ROLE (mis_stamped_canonical_base, consulted at
open and commit -> read-only + UnsupportedCanonicalChunkMajor;
regression test covers commit and reopen).

Also: three stale-doc fixes (decode_canonical now "current (schema
major 2)"; CreateRegionOp + StagedChunk::operation_block +
stage_operation_block docs describe minimal stamping, not just "v1
CreateRegion").

Full gate green: fmt, clippy -D warnings, rustdoc -D warnings, 30
workspace suites, conformance scale 1 (8/8).
