feat(cognition): fail-closed linguistic governance + trilingual constraint pipeline

Close residual answer-authority debt: typed CoherenceRefusal/ContractViolation/
FieldFailure, structured ProofTrace (atoms→operators→closure), and Shadow Gate
paths that refuse certified answers when contract_assessment is None or geometry
is open. Add shared semantic primitives and Layers A/B/C (English/Hebrew/Koine)
as constraint producers only, with Cl(4,1) structure-sensitive embedding (no
unitize in generate/), three field outcomes, and an articulation firewall that
blocks payload-value citation bypass and uncertified content.
