Flow Plugin System

Flow provides a standardized plugin interface (FlowPlugin / PluginManager) for extending capabilities like Minimap, Controls, Grid, Snap, and Export.

Using Plugins

Plugins can be registered using the usePlugin method. Most built-in features have been migrated to the plugin system.
