In high-frequency trading (HFT), dynamic memory allocation is often avoided on the critical path to prevent latency spikes caused by system calls. A stack-allocated array provides predictable, ultra-low latency while still offering dynamic resizing up to a strict maximum capacity. Task Implement a StackArray<T, Capacity> template class that provides a dynamically sized array backed by a fixed-size stack allocation. Your class should implement the following methods: - StackArray(): Initializes
