Module plugins 

Plugin system for extending agent capabilities at runtime.

Plugins provide a structured way to bundle and manage extensions that add tools, middleware, state transformers, or event handlers to a running agent.

The PluginRegistry manages plugin lifecycle (load, activate, deactivate, unload) and supports dependency resolution via topological sorting.
