- Add FFI wrappers for all EskinDeviceFunc trait methods: eskin_read_hdw_version, eskin_read_matrix_row/col, eskin_read_device_config1/2, eskin_write_device_config1/2, eskin_write_matrix_row/col - Extract sdk_error_to_code() helper for SdkError -> SdkErrorCode conversion - Update C header (include/eskin_ffi.h) with new function declarations - Update Python FFI bindings (example/python/eskin_ffi.py) with new methods - Update README with Python usage instructions and full FFI interface table
