Add a new plate washing module with a backend for the BioTek EL406 plate washer, communicating via FTDI USB serial interface. Architecture: - PlateWasher resource and PlateWasherBackend base class - BioTekEL406Backend composed from mixins: Communication, Queries, Actions, and Steps (manifold, peristaltic, syringe, shake) - Binary protocol with framed messages, ACK/NAK flow control, and async status polling for long-running operations Features: - Manifold wash/dispense/aspirate/prime/auto-clean operations - Peristaltic pump prime/dispense/purge with column/row selection - Syringe pump dispense/prime with column selection - Plate shaking with configurable intensity and duration - Device queries (manifold type, serial number, sensor status) - Action commands (abort, pause, resume, reset, self-check) - 160+ device error codes with descriptive messages - MockFTDI test double for hardware-free testing 374 tests covering all operations, wire format encoding, parameter validation, communication protocol, and error handling.
