test: add P0 test blitz — 177 cross-cutting tests + 27 benchmarks

Aspect-oriented test suite covering the 5 cross-cutting concerns:
- Contractiles post-processing (M1–M5 governance pass, 11 contract evaluators)
- Panel Bus event propagation (subscribe/unsubscribe, topic routing, batching)
- Anti-Crash gate validation (security/type/logic constraints, review state machine)
- Orbital drift detection (divergence, stability bounds, humidity feedback)
- TypeLL cross-panel type checking (kernel, disciplines, narratives, filtering)

Plus end-to-end message round-trip tests (multi-domain cascades, governance
convergence, recovery paths, state invariants) and TEA update cycle benchmarks
(per-domain dispatch latency, full round-trips at 10/100 msg sustained load).

2462 tests passing, 0 failures (up from 2285).

+ * Anti-Crash Gate Cross-Cutting Tests — aspect-oriented verification of
+ * the logical circuit breaker for neural token validation.
+ *
+ * Tests the full validation pipeline:
+ *   - Security constraint checking (eval, exec, rm -rf, DROP TABLE, <script>)
+ *   - Type constraint checking (forbidden patterns, reserved keywords)
+ *   - Logic constraint checking (boolean contradictions, negations)
+ *   - Review/approve/reject state machine
+ *   - Halt/clear lifecycle
+ *   - Integration with Update cycle
+ *   - Throughput under adversarial input
+ *
+ * ReScript compilation notes:
+ *   processToken returns [state, token | undefined] (tuple → JS array)
+ *   validate returns "Valid" | { TAG: "Invalid", _0: reason } | { TAG: "RequiresReview", _0: reason }
