datalog: magic regression tests from bug-hunt round (242/242)
Bug-hunt round probed magic-sets against many edge cases. No new
bugs surfaced. Added regression tests for two patterns that
exercise the worklist post-fix:

- 3-stratum program (a → c via not-b → d via not-banned).
  Distinct rule heads at three strata; magic must rewrite each.
- Aggregate-derived chain (count(src) → cnt → active threshold).
  Magic correctly handles multi-step aggregate dependencies.

Magic-sets is robust against: 3-stratum negation, aggregate
chains, mutual recursion, all-bound goals, multi-arity rules,
diagonal queries, EDB-only goals, and rules whose body has
identical positive lits.
