⚠️ Breaking: Unified Bit Type API

acquire!(pool, Bit, n) now returns BitVector instead of SubArray{Bool}.

Why: Native BitVector utilizes SIMD-optimized chunk algorithms, making operations like count(), sum(), and bitwise broadcasting 10×–100× faster compared to SubArray{Bool} views.

# Before (v0.1.1): Returned SubArray{Bool}
# After  (v0.1.2): Returns native BitVector (SIMD optimized)

@with_pool pool function foo()
    bv = acquire!(pool, Bit, 10_000)

    # Operations using packed bits are significantly faster
    c = count(bv)  # 10x~100x speedup vs view behavior
end

Migration: No code changes needed for typical usage. Only affects code explicitly type-checking for SubArray.

What's New

BitVector Pooling

Memory-efficient pooling for boolean arrays using Julia's native BitVector storage. Reduces memory usage by ~8x compared to Vector{Bool}.

@with_pool pool begin
    # Packed storage (1 bit per element)
    mask = acquire!(pool, Bit, 1024)

    # N-dimensional support
    grid = acquire!(pool, Bit, 128, 128)
end

Convenience Functions

New trues! and falses! functions for drop-in replacement of Base allocations:

@with_pool pool begin
    mask = falses!(pool, 1024)      # All false
    flags = trues!(pool, 10, 10)    # All true, 2D
end

These mirror Julia's trues() and falses() with pooled memory management.

Memory Comparison

Type	Storage	Memory (1024 elements)
Vector{Bool}	1 byte/element	1024 bytes
BitVector	1 bit/element	128 bytes
