extends RefCounted
## Presenter for the toolkit's two editor-global dialogs — Info / Help and the
## extension catalog.
##
## Editor-global means the dialogs parent to the editor base control, not to the
## dock: they are reachable from any surface (dock footer, Tools menu, onboarding
## wizard), so their creation, reuse, and teardown belong to this shared
## presenter, not to the dock — the dock is a UI surface, not a service locator.
## Each dialog is created on first show and reused afterwards (a reopened dialog
## keeps its window state); the owner must call [method dispose] during teardown.
##
## Editor-only: names EditorInterface, so this script must never enter the
## runtime autoload's preload closure.

## Free both dialogs and drop the references. Must run during the plugin's
## synchronous teardown, and must free immediately (never queue_free): the
## dialogs are base-control children nothing else frees, and a deferred free at
## process exit may not flush before ObjectDB's exit-time leak check runs.
