imccyu 4a27da44cf test(web): real-composition webserver spec
Boots a test-only cordis.yml through the real Loader and asserts the route
service's behavior surface: exact/longest-prefix matching, tapIndex
transform order and unsubscription, traversal 403, non-GET 405, SPA-200
fallback, malformed-request 400 without process exit, duplicate-pattern
throw, dispose closing held connections with register/disposer symmetry,
and a listen-failure fail-loud case (EADDRINUSE -> FAILED fiber + late
rejection). Replaces the retired factory-era specs.

/**
* REAL-composition coverage: a test-only cordis.yml booted through the
* vendored Loader mounts the webserver row, and every assertion observes the
* user-visible HTTP surface of the running server (routing precedence, index
* taps, static-fallback semantics, per-request error containment, teardown).
