[dependabot]

Bumps stringzilla from 3.12.6 to 4.6.0.

Release notes

Sourced from stringzilla's releases.

v4.6: Fast Search for Georgian & Hashing w/out Stack Protection 🔞

• New fast case-insensitive substring search path for Georgian 🇬🇪
• Faster hashing with compile-time dispatch w/out stack protection 🔞
• Faster byteset search on Haswell CPUs, thanks to @​Caturra000 👏
• Fewer inline-related warnings in C++ builds, thanks to @​inflooper 👏

Minor

• Add: Georgian fast path (e02cb00)

Patch

• Fix: inline static warnings with C++23 modules (#287) (374adbf)
• Improve: Reduce startup overhead for sz_find_byteset_haswell (#293) (7f2899a)
• Fix: Missing Georgian dispatch (5f91e7e)
• Improve: Drop stack-protection in hashing on GCC (23801e4)
• Improve: Reduce repeated reviews (2e5784b)
• Improve: Faster sz_size_bit_ceil (4003057)
• Improve: Avoid ZMM-to-stack spill in Skylake comparisons (d94a010)
• Make: Use relative install path for C sources (690d775)

v4.5.1: UTF-8 "Find-All" Iterators for Python 🐍

Patch

• Fix: Shared library function signatures (4b6f40f)
• Make: Ignore blaming for recent chores :) (8a4cacd)
• Fix: Cleaner haystack/needle buffer (de44c05)
• Improve: Python iterator over case-insensitive matches (3782f9a)
• Make: NPM Trusted Publishing in CI (738b07f)

v4.5: 50x Faster Case-Insensitive Search for All of Unicode 17 in AVX-512

Below are the performance numbers comparing the search throughput of unique "word" tokens across various languages of the Leipzig Wikipedia Corpora for a case-insensitive substring search that respects all Unicode 17.0 case-folding rules. This is arguably the only library providing full Unicode spec compliance for search operations besides the PCRE2 library, which is often order(s) of magnitude slower than even our serial baseline due to the extreme complexity of combining a complete RegEx engine with Unicode compliance.
