feat(ai-sdk): IACE warewashing hazard patterns + cross-domain gating

Add commercial-dishwasher hazard patterns (HP2200-HP2206): hot-water/steam
scald on door opening, hot surfaces, hot ware, corrosive detergent/rinse-aid
burn, respiratory irritation, door pinch and wet-floor slip — each gated by
dom_warewashing so they never leak into other machine classes. Add the
matching warewashing protective measures (M2200-M2208).

Tighten capability-domain gating: emit dom_flame/dom_glue and add welding
surface-form gate terms (schweissarbeitsplatz, schweissfunke, lichtbogenzone,
...) so the welding/flame/glue burn patterns stop leaking into thermal-capable
machines such as a dishwasher.
