gg_hash

Added

• Add a ggHash method and a hashJson method to allow to create 128 bit hashes on arbitrary strings and hash JSON files
• Add example code
• Add .gitattributes file
• Add benchmarks and golden checks (benchmark/)

Changed

• Improve performance of fnv1 and hashJson significantly while keeping all hashes bit-identical: fnv1 no longer copies 8-byte-aligned typed data whose length is not a multiple of 8 and uses specialized loops for lists; hashJson hashes in a single pass, serializes JSON directly to reusable UTF-8 buffers and uses a built-in, allocation-free SHA-256
• Move the crypto package from dependencies to dev_dependencies; it is only used in tests now to verify the built-in SHA-256
• Optimize performance using claude

Removed

• dependency pana
