Important notes

• FixedVersion can be null/None (not just missing) when no fix is available
• FixedVersion may contain comma-separated values for multiple fix branches (e.g., "7.5.2, 6.3.1, 5.7.2")
• CVSS dict keys vary per vulnerability — not all sources are present for every CVE
• Title may be null; fall back to Description if so
• Vulnerabilities key may be null (not just empty list) if no vulns found for a target
