feat(cra): SBOM- + DAST-Findings aus dem Scanner-MCP konsumieren

Sharangs compliance-scanner-agent exponiert SBOM (sbom_vuln_report) + DAST
(list_dast_findings) als eigene MCP-Tools (nicht via list_findings). Neuer
fetch_all_findings(repo_id) zieht list_findings + SBOM + DAST in EINER
MCP-Session und normalisiert ins Finding-Schema:
- SBOM: ein Finding pro verwundbarem Paket (nicht pro CVE), cwe=CWE-1395
  -> deterministisch CRA-AI-22 (robust gegen Paketnamen wie "sqlite").
- DAST: cwe/endpoint/vuln_type uebernommen -> Mapping via cwe/keywords.
assess-from-scanner nutzt fetch_all_findings + liefert source.breakdown
(code/sbom/dast). DAST hat im MCP keinen repo_id-Filter -> dast_repo_scoped:false
(deployment-weit, transparent geflaggt).

Echte MCP-Daten: Kitchenasty 58 code + 35 sbom + 81 dast -> 174 gemappt
(Coverage 94,3%, alle 35 SBOM -> CRA-AI-22).

Enthaelt zusaetzlich das Qdrant->Prod-Kopierскript (#42, verbatim macmini->prod).
