[pitboss] phase 13: Track L.11 — Express / Koa / NestJS / Fastify adapters

+//! Phase 13 (Track L.11) — JS framework adapter integration tests.
+//!
+//! Each test exercises `detect_binding` end-to-end against a fixture
+//! file under `tests/dynamic_fixtures/js_frameworks/`, asserting that
+//! the right adapter fires, the binding carries
+//! `EntryKind::HttpRoute`, and the `RouteShape` + per-formal
+//! `request_params` match the brief's contract.  Benign fixtures must
+//! produce the same adapter binding shape as the vuln fixtures — the
+//! adapter only models the route, the differential outcome of a
+//! verifier run is what distinguishes the two.
