Loader result that carries optional metadata about how the plugin was sourced.
dev: true marks a plugin as session-only and triggers shadow-on-id-collision
inside the manager: if a plugin with the same id is already registered (a
builtin, or a previously-installed plugin from the registry), the dev plugin
temporarily takes over that id slot. The original is restored when the dev
plugin is removed (or on page reload, since dev plugins aren't persisted).
