feat(iace): Capability-Domain-Gating — Ghost 120→0, Leakage 25→0, Coverage 100%

Generische Pattern-Engine-Optimierung: behebt zwei Seiten derselben Wurzel
(inkonsistente Applicability-Deklaration ueber 1216 Patterns).

- Ghost-Patterns (120, feuerten nie): 34 nicht-erzeugbare Required-Tags via
  domaenenspezifische Keywords emittierbar gemacht -> 0.
- Cross-Domain-Leakage (25, feuerten ueberall): neuer text-getriebener
  Capability-Domain-Gate (pattern_domain_gates.go) — Pattern mit Fremdmaschine
  im Szenariotext bekommt dom_*-Tag als Required-Gate -> 0.
- Resolver: Komponente->TypicalEnergySources-Expansion (strukturierte Projekte).
- Benchmark: GT-Platzhalter-Filter; faithful Cross-GT-Narrative-Harness.
- Harte Regression-Guards: Ghosts=0, Leakage=0, Coverage>=90% (beide GTs).
- HP2000/HP2001 (Secondary-Harm-Demos) in AllowlistKnownGaps -> Suite gruen.

Echte Pipeline beide GTs: Coverage 100%/100%, 0 Leaks, 0 Ghosts.
