- Sets up API server as source of truth for installation root, similarly to what was done for the data root. `system start` establishes the install root, setting the environment variable `CONTAINER_INSTALL_ROOT` when launching the API server. - The API server propagates the environment variable when launching helpers, and returns the install root to the CLI via the health check XPC. - Includes several fixes for detecting plugins that use app bundle layout.
