- engine: bump cacheVersion v86 → v87 so cached Python snapshots re-extract

  with the tightened resolveCall (extractor output changed).
- docs: refresh the Apache Airflow --explain report in README.md to match
  current output (fact count + god-class/call-graph-hotspot counts).

 Every finding carries a confidence score, and it means something exact: `1.0` is a structural fact (a cycle exists; an export ratio measured), while anything below is a flagged heuristic for you to review (a god class is a statistical fan-in outlier, not a rule). The analyses are computed by graph algorithms — Tarjan's SCC for cycles, longest-path for dependency depth, mean+2σ outlier tests for the rest — so the same commit yields the same report.
