TwoTrees SK1: reconstructing the display UART interface

TwoTrees SK1 display research documents the printer's HMI UART commands and incoming touch, numeric and startup frames. The repository uses that mapping in a Rust client connected to Moonraker, a Python demonstration host and an experimental ESP32-C6 display client.

Requirements & limits

Prerequisites: The TwoTrees SK1 display uses 5 V power and 3.3 V RX/TX logic levels.
Scope: The Rust client targets the printer's HMI UART and Moonraker; the ESP32 client targets ESP32-C6.
Limits: The protocol manual includes probe and debug commands that require checking on a live HMI.
