Detailed Description

Coordinates NETCONF-based communication and TSN configuration workflows across topology nodes.

This class manages per-node NETCONF sessions, retrieves operational LLDP and GCL data, and applies generated TSN/GCL configuration back to devices. It serves as the orchestration layer between topology state, inventory credentials, XML builders/parsers, and device-facing NETCONF operations.
