Moderate signal

editorial:auto 2d

MigraDiff v1.1.0 introduces JSON output with per‑statement risk classification and several usability improvements, but it requires uninstalling the original migra before installation.

Why it matters: The release adds structured diff output (severity 30) for automated CI integration and mandates a breaking change: uninstall the prior migra package before installing migradiff (severity 70).
