// Benchmark: SmallVec vs Vec for small allocations
//
// This benchmark validates Phase 8 optimization by comparing:
// - Vec<T>: Always heap allocates
// - SmallVec<[T; N]>: Stack allocates for small sizes, heap for large
//
// Expected result: SmallVec should be faster for small collections (< 8 elements)
