v3.5.0

• New agent output format: one stable contract per finding — { id, severity, confidence, exactEdit, manualFix, verify } — so an AI agent applies the exact edit and runs the verify step to prove the fix, instead of parsing prose
• Available via check --format agent and the scan_file tool (format: agent); deterministic, no new dependency
• No rule or tool changes (438 / 37); gate green (PASS/A/0)
