Detailed Description

ROS 2 lifecycle node that manages sensor fusion in Easy Navigation.

Collects, transforms, and publishes fused perception data from multiple sources. Sensor handlers are loaded at runtime as pluginlib plugins, allowing users to add new sensor types without modifying this node.
