Empty/nil input now returns (nil, nil) on no-CGO builds so callers can skip empty blocks without distinguishing build modes. Non-empty input returns the new exported ErrEcrecoverNoCGO sentinel for fallback paths. Pin the Signature and EcrecoverResult layouts (R/S/MsgHash 32 bytes, Address 20 bytes, V/Valid scalar) and the empty-batch contract for both build paths.
