zlib interop checker

This helper verifies interoperability between:

• V module: compress.zlib
• C helper linked with libz
• Python stdlib: zlib It runs deterministic test vectors, compresses each vector with all three producers, then cross-decompresses every produced stream with all three consumers. A case passes only if every decompressed output is byte-identical to the original input.

Run

./vnew run vlib/compress/zlib/interop/zlib_interop.vsh

Requirements

• python3 with the stdlib zlib module
• a C compiler (cc, gcc, or clang)
• libz development headers and linker support (-lz)
