Bill 84708da611 Sprint 282: Polyglot test harness (steps 1938–1942)
PolyglotSpecRunner, BehavioralParityChecker, ParityRegressionGuard,
PolyglotSuiteOrchestrator — 26/26 tests pass.
Integration step 1942: poly-sort Python+Rust+Go parity verified.
Metrics: 7 whetstone calls, 8855 tokens.

// Step 1939: BehavioralParityChecker
//
// t1: check — all match → allMatch=true, empty divergentLanguages
// t2: check — one diverges → allMatch=false, divergentLanguages lists it
// t3: checkAgainstReference uses named language as reference
// t4: allPass — true when all ran+match; false when one doesn't run
// t5: failingLanguages returns divergent set
