Replace std::vector usage in put-signal host proxy transport API with pre-allocated C arrays to eliminate dynamic memory allocation overhead. The previous implementation used std::vector because the number of writes per put-signal operation varied based on buffer mapping across memory regions. This change pre-allocates fixed-size arrays (max 256 writes) during proxy initialization, providing a small latency improvement for put-signal operations.
