feat(iace): generic cross-domain leak gates + norm vocab reconciliation

- Domain-gate ~15 foreign machine classes (pool, amusement, paint booth,
  tank farm, reactor, lathe/chips, saw, film/carton, robot, mobile cab,
  asbestos, playground swing) in pattern_domain_gates.go so ungated hazard
  patterns stop leaking into unrelated machines; matching emit keywords
  added in keyword_dictionary.go (gate+emit share one vocabulary).
- Extend the cross-domain precision guard to 6 machine classes (press,
  cobot, motor, welding + the 2 GTs) with per-case homeDomains, so a
  machine's own domain terms are never flagged. GT coverage stays 100%.
- Reconcile the fine-grained norm machine-type vocabulary (455 keys) with
  the 68 canonical dropdown keys via canonicalMachineType() family folding
  in matchNorm — welding 0->17, robotics_cobot 0->6, press 8->13,
  circular_saw 1->35 machine-specific C-norms. Pattern gating left strict.
- Fix initialize?force=true summary index-shift that mislabeled counts
  (reported matched-patterns as "hazards"); now uses named step vars.
