Close all 26 generator readiness gaps (sprints 267-270)

Sprint 268: GR-002/003/006/007/008/016/017/019/021/024 — self-containment,
  graduation thresholds, asm/ir/jvm/elixir lang coverage, semanno format.
Sprint 269: GR-005/011/013/015 — prose capture in RequirementsParser,
  GateEnforcer, ParitySkewAnalyzer, CrossArtifactConsistencyEngine.
Sprint 270: GR-009/010/012/014/018/020 — CrossFileTransactionGate,
  SemanticCompletionGate, ConstrainedProjectionGate, TokenBudgetGate,
  CppConstraintRefactorPolicy, NativeDecompositionDepthGuard.
All 50 new tests passing (steps 1873-1882, 5/5 per step).
