[1.57.2] - 2026-08-02

Fixed

• macOS app: remove invalid --format json flag from PolicyServiceDelegate
  that caused the WebKit governance extension to fail open (every web flow
  was allowed by default).
• Infer proxy gate: test isolation — use fresh in-memory AuditTrail to
  prevent prior approval records from the default SQLite DB from leaking
  between test runs.
