feat(cra): Maßnahmen-Provenienz + Lizenzklasse je Normquelle

Jede Normreferenz einer Maßnahme wird lizenzklassifiziert (eu_law / public_domain / open / paid_reference) — paid-reference-Normen werden nur als Verweis geführt, nie im Text gespeichert (idea/expression). Kuratierte Maßnahmen tragen Tier 'core', KI-/Fallback-Maßnahmen 'review' (indikativ). Frontend zeigt Quellen-Badges + "indikativ"-Kennzeichnung. Methodik in docs-src/development/mapping-methodology.md (Szenario C, Due-Diligence). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

+"""Provenance / license classification for norm references.
+
+Encodes the BreakPilot mapping methodology (idea/expression): a *reference* to
+where a topic sits in a standard is a fact and citable; the paid normative *text*
+is never stored or reproduced. This classifier marks which sources are freely
+usable (EU law, US-gov public domain, open licenses) vs. paid standards we may
+only REFERENCE by clause/control ID.
+
+See docs-src/development/mapping-methodology.md.
