fix: address review round four

- the cached-identity rung gains a finality gate: the identity value
  carries its descriptor seq and a cached row is served only when that
  seq lands in the child's own suffix, so a fork seed's replayed
  ancestor identity can never outrank the authoritative refold
  (stateVersion bumped for the state-shape change)
- the cold preparation validates the inspected header against the
  enumerated candidate's lifecycle witness; a republished id degrades to
  that child's corrupt diagnostic instead of leaking the new owner's log
- the new projection registration proves HMR disposal; companion notes
  qualify the superseded decision text and record the deliberate
  error-face asymmetry
