+Panels, overlays, and menus are loaded when summoned. Plugins can set the top-level manifest key `keepLoaded: true` to survive between summons, and to keep a service mounted across plugin hot-reload (so `omarchy.lock` is not destroyed while Hyprland still holds the session lock). First-party services are loaded at startup.
 
 Entry points are QML `Item`s. Panel, overlay, and menu entry points expose `open(payloadJson)` and `close()` for summon/hide; on load the host injects `omarchyPath`, `shell`, `manifest`, and the registries (`pluginRegistry` / `barWidgetRegistry`) as properties. Built-in plugins receive the trusted host objects. Third-party plugins receive capability-scoped facades instead: ordinary plugins may look up and control only their own service and lifecycle, menu plugins receive an application-library facade, and plugins can read detached scalar bar state. A full-bar plugin additionally receives detached bar configuration and widget-catalog snapshots, narrow proxies for the non-authentication services used by built-in bar widgets, and lifecycle control over configured non-authentication UI plugins. Authentication capabilities are stamped from trusted first-party manifests, authentication services are kept out of the host's public service map and QML object tree, and third-party registry snapshots can be changed only locally without mutating the host registries.
