feat(schema/adjust): schema_version on 4 reports + adjust-check recipe

hyperpolymath · claude · hyperpolymath · commit 320256b651cf · 2026-04-27T19:29:08.000+01:00
- Add `schema_version: String` with serde(default) to CrashReport,
  AxialReport, AmuckReport, AbductReport — closes the 4-report gap
  identified in the schema-versioning audit
- Update every construction site (executor, engine, ambush, panll,
  a2ml, adjudicate, amuck, axial, abduct)
- Add 6 new seam_contract_tests entries: schema_version present/default
  for each of the 4 new report types; all 16 seam tests green
- Add ADJUST contractile recipe to contractile.just: verifies PA006
  production/test thresholds and suppression-rule count match
  Adjustfile.a2ml at every `just` run
- Update Adjustfile.a2ml active-rules 13 → 17 (4 rules added since
  last sync); fix stale comment in kanren/core.rs
