feat(canonical-controls): Canonical Control Library — rechtssichere Security Controls

Eigenstaendig formulierte Security Controls mit unabhaengiger Taxonomie
und Open-Source-Verankerung (OWASP, NIST, ENISA). Keine BSI-Nomenklatur.

- Migration 044: 5 DB-Tabellen (frameworks, controls, sources, licenses, mappings)
- 10 Seed Controls mit 39 Open-Source-Referenzen
- License Gate: Quellen-Berechtigungspruefung (analysis/excerpt/embeddings/product)
- Too-Close-Detektor: 5 Metriken (exact-phrase, token-overlap, ngram, embedding, LCS)
- REST API: 8 Endpoints unter /v1/canonical/
- Go Loader mit Multi-Index (ID, domain, severity, framework)
- Frontend: Control Library Browser + Provenance Wiki
- CI/CD: validate-controls.py Job (schema, no-leak, open-anchors)
- 67 Tests (8 Go + 59 Python), alle PASS
- MkDocs Dokumentation
