Function auth_router 

pub fn auth_router() -> Router<AppState>

Returns a single router containing all atrg built-in auth routes: /auth/*, /client-metadata.json, and /.well-known/oauth-protected-resource.

This is the recommended way to wire auth into atrg_core::AtrgApp:

use atrg_core::AtrgApp;

AtrgApp::new()
    .with_auth_routes(atrg_auth::routes::auth_router())
    .with_cleanup_task(atrg_auth::routes::spawn_cleanup_task)
    .run();
