Rewrite every protocol driver page (zh+en) into a four-section structure
— protocol background, attribute config, troubleshooting, and how it lands
in DC3 — cross-linked to the foundations network-layer chapters and the
driver capability matrix. Implementation status is verified against each
driver's source and labeled honestly (skeleton: ethernet-ip, iec104, dlms,
can, zigbee; partial: fins, mqtt, lwm2m, virtual). Add foundations
back-links from the concepts and drivers hubs to close the theory↔practice
loop.
