Samsung Washer Monitor: reconstructing a washer panel UART feed

Samsung Washer Monitor for ESPHome decodes the receive-only UART stream between a Samsung WW11BGA046 washer's DC92-01950B panel and main board. Its ESPHome component exposes program selections, displayed time, indicators and inferred cycle status to Home Assistant. The documentation records connector observations, wiring and the limits of the author's single-machine testing.
