Module lifecycle 

Plugin lifecycle state machine.

Each plugin moves through a defined lifecycle:

  Loaded → Linked → Initialized → Active → Draining → Removed

The state machine is encapsulated here so hot reload (M10 cutover) can drain in-flight references through Arc::clone semantics before swapping in the new instance.
