What's Changed

Bug Fixes

• Fixed SIMD entropy encoder DC double sign adjustment bug - The SIMD encoder was incorrectly applying sign adjustment twice to DC coefficients (once during zigzag reordering and again in encode_dc_fast), causing image corruption particularly visible in 4:2:0 subsampling mode with Huffman optimization enabled.

Performance

• Rust 1.65-2.57x faster than C mozjpeg with identical settings (4:2:0, Robidoux tables, Trellis AC+DC, Huffman optimization, Deringing)

Dependencies

• Integrated archmage 0.1.0 for safe SIMD capability tokens

Other

• Fixed clippy warnings in examples and tests
• Added apples-to-apples timing benchmark (examples/timing_benchmark.rs)

Benchmark Results (v0.5.1)

Apples-to-apples comparison with identical settings:

Image Size	Rust	C mozjpeg	Speedup
768x512	25.5ms	42.0ms	1.65x faster
2048x2048	426ms	1096ms	2.57x faster
