The merge-time items from the #381 review. navigator.sendBeacon is not fetch,
so the base-aware wrapper never saw the two crash-diag beacons and a sub-path
install posted them to the origin root every two seconds. The test suite now
strips CODEMAN_BASE_URL like CODEMAN_GESTURE, since the constructor reads it
as a fallback and an operator who exports it would see the root-install
byte-identity assertions fail. test/base-path-server.test.ts boots a real
WebServer under /codeman and checks the ingress strip, the base injection,
the rebased redirects, the 404 envelope and a prefixed WebSocket upgrade.
