    vendor/ZLIB: Upgrade from 1.3.1 to 1.3.2
    
    Version 1.3.2 (released on 2026-02-17) has these key updates from 1.3.1:
    
    * Address findings of the 7ASecurity audit of zlib.
      - Check for negative lengths in crc32_combine functions.
      - Copy only the initialized window contents in inflateCopy.
      - Prevent the use of insecure functions without an explicit request.
      - Add compressBound_z and deflateBound_z functions for large values.
      - Use atomics to build inflate fixed tables once.
      - Add --undefined option to ./configure for UBSan checker.
      - Copy only the initialized deflate state in deflateCopy.
      - Zero inflate state on allocation.
      - Add compress_z and uncompress_z functions.
    * Complete rewrite of cmake support.
    * Remove untgz from contrib.
    * Vectorize the CRC-32 calculation on the s390x.
    * Remove vstudio projects in lieu of cmake-generated projects.
    * Add zipAlreadyThere() to minizip zip.c to help avoid duplicates.
    * Add deflateUsed() function to get the used bits in the last byte.
    * Fix bug in inflatePrime() for 16-bit ints.
    * Add a "G" option to force gzip, disabling transparency in gzread().
    * Return all available uncompressed data on error in gzread.c.
    * Support non-blocking devices in the gz* routines.
