Module app 

Launch contract.

Boot phases (executed strictly in this order — order matters):

1. Collect inventory-registered providers + routes.
2. Run each plugin’s on_init with a mutable ArclyPluginContext — plugins may queue providers (provide<T>), routes, global interceptors, OpenAPI mutators.
3. Apply queued provider closures to the DiContainerBuilder.
4. Freeze. The container becomes &'static, lock-free for reads.
5. Build the OpenAPI spec, run plugin spec-mutators, leak it as &'static.
6. Mount macro-registered routes, then plugin-registered routes.
7. Bind the listener.
8. Run each plugin’s on_start(&container) — background tasks spawn here.
9. Serve. Ctrl-C / SIGTERM triggers axum’s graceful shutdown — accepts stop, in-flight drain. Only after that completes do plugin on_shutdown(&container) calls run, wrapped in a 5-second timeout so a wedged plugin can never wedge the process.
