feat: cross-runtime differential conformance + guard totality fix - #118
Merged
Conversation
Adds Trax.Effect.StateMachine.Testing, a framework-agnostic harness that replays a TypeScript-generated differential corpus through the C# engine so the two engine ports are proven behaviorally identical (PD1). Also closes a totality gap the differential surfaced: Advance evaluated guards outside its try/catch, so a throwing guard escaped instead of degrading to internal-error (PD4). Guard evaluation now runs inside the backstop, matching the TypeScript engine.

… path Direct unit tests for the shipped Replay over an inline corpus (transition/rejection match + both mismatch paths), so it is covered in isolated CI where the conformance test skips for lack of the shared goldens. Plus a guarded edge with no GuardMessage to exercise the generic guard-failed fallback.
