-- Unified public native/Python option validation and removed AWIF from performance benchmarks.
 - Added NEON (ARMv8) and AVX2 (x86-64) SIMD acceleration for CRC-32 checksums and predictive filter encoding.
 - Added content-adaptive wavelet quantization that scales with local tile detail.
 - Improved Zstandard compression levels for all search presets (Fast 1→3, Balanced 6→9, Extreme 15→19).
