refactor(modbus): switch to native Modbus TCP protocol

Browse Source 
Switch from Modbus RTU over TCP to native Modbus TCP based on hardware
testing. Uses standard MBAP header (no CRC16), port 502, and TCP-only
tokio-modbus feature for simpler implementation.

Updated: Cargo.toml, plan.md, research.md, tasks.md
