The merge's "always pass adapter-resolved host/port to AppCLIEntry" made the adapter's 127.0.0.1/3080 shadow apps/cli/cordis.yml's webserver row — editing the yml port would have had no effect, a duplicated default. The adapter now assigns no host/port default: an absent --host/--port leaves the field undefined (WebInvocation.host?/port?), runWeb forwards each to AppCLIEntry only when present, and AppCLIEntry patches the webserver row only for an explicit flag. cordis.yml is the single source of the host/port default; the adapter still validates a flag when given. Removes the now-unused DEFAULT_WEB_PORT; LOOPBACK_HOST/ALL_INTERFACES_HOST stay as the allowed-value vocabulary (validation + the printed URL/LAN line).
