The single-message case (via write_protobuf_packet) is the most common path. Peeling the first loop iteration and outlining the multi-message batch path avoids the ~300-byte StaticVector<iovec> stack allocation on the hot path. Plaintext write_protobuf_messages: - Stack frame: 352 → 64 bytes - Code size: 246 → 127 bytes Noise write_protobuf_messages: - Extracted encrypt_noise_message_ helper for reuse - Same peeling pattern with outlined batch path
