Fredrik Johansson 697a7e614d fix: challenge nonce must be 32 bytes per YAW/2 §5.1 ...

The anchor was sending a 16-byte nonce. The spec (yaw2.0-protocol.md §5.1
and yaw2-implementation.md §7.1) requires 32 bytes. Any spec-conformant
peer would fail join signature verification against this anchor, breaking
interop. Signature verification was already using the raw nonce bytes
(not hex), so only the allocation size needed changing.
