	ActivationDispatch.h
	Function-pointer types and ActivationType <-> function dispatch tables shared by every activation family. Forward-declares the concrete activation functions (defined in the sibling Relu.h/Gelu.h/Tanh.h/ Sigmoid.h/Linear.h) so the dispatchers below can take their addresses without depending on inclusion order.
	ActivationMacros.h
	The RESTRICT portability macro shared by every activation header. Split out so each per-activation header is includable on its own, without relying on include order through the Activations.h umbrella.
	Gelu.h
	GELU (tanh approximation) and its derivative (plain and two-buffer variants), with AVX512/AVX2/SSE paths and a scalar tail.
	Linear.h
	The identity activation and its (constant) derivative.
	Relu.h
	ReLU and its derivative (plain and two-buffer variants), with AVX512/AVX2/SSE paths and a scalar tail.
	Sigmoid.h
	Logistic sigmoid and Elliot ("fast") sigmoid, and their derivatives (plain and two-buffer variants), with AVX512/AVX2/SSE paths and a scalar tail.
	Tanh.h
	tanh and its derivative (plain and two-buffer variants), with AVX512/AVX2/SSE paths and a scalar tail.
	VectorMath.h
	SIMD-vectorized exp/log helpers (AVX512/AVX2/SSE with a scalar tail). Currently unused by the rest of the codebase – kept for planned future use (e.g. a vectorized softmax path) rather than deleted.
