Module collections 

High-performance collections backed by explicit allocators.

Unlike std::collections, every type in this module:

1. Never uses a global allocator. Each collection accepts an Allocator reference at construction time and routes all allocations through it.
2. Provides SIMD-accelerated operations (fill, search, copy) where applicable via the internal simd module.
3. Decouples data from logic via context traits: hashing and ordering are provided through HashContext and OrdContext rather than via Hash / Ord bounds. This allows domain-specific algorithms without wrapper types.

Collection Overview

Type	Description
ExVec<T>	Growable contiguous array
ExBox<T>	Single heap-allocated value
ExString	Growable UTF-8 string
ExHashMap<K, V, C>	Swiss-table open-addressing hash map
ExPriorityQueue<T, C>	Binary-heap priority queue
ExBoundedArray<T, N>	Fixed-capacity stack-allocated array
