Detailed Description

Virtual (host-side) shift-register driver for unit testing.

Maintains a byte-shadow array mirroring what a real 74HC595 chain would hold. No hardware is touched; used by the host test suite. Individual bytes are inspectable via byteAt() to verify bit-packing logic.

Bit packing: output index idx maps to byte idx/8, bit idx%8 (LSB = bit 0). The mapper function must return indices in [0, nOut).
