aimuz be50b58d70 internal/zstd: optimize window reset using make for buffer allocation
Optimize the zstd window's reset function to use `make` for buffer
allocation when needed. This ensures efficient memory usage by
conditionally reallocating the buffer based on its capacity, improving
performance in scenarios where the existing buffer is insufficient.
