feat: add --direct-enter option to skip to world scene

Support a new CLI flag that launches the app directly into the world scene. If no IP is provided, it starts a local server on the specified port and connects to 127.0.0.1; otherwise it connects to the given IP. With this flag enabled, a port must be specified via -p. Also expose SceneManager::push as public so scenes can be pushed immediately when bypassing the normal menu flow.
