fix: download zlib from zlib.net/fossils (root URL now 404s)#1
Merged
Conversation
zlib.net only serves the current release at the root path; older versions are moved to the permanent /fossils/ archive. zlib 1.3.2 is now current, so https://zlib.net/zlib-1.3.1.tar.gz returns 404, which made wget write no file and the subsequent `tar xzf zlib-1.3.1.tar.gz` fail, breaking the gocr WASI build. Point the pinned 1.3.1 download at /fossils/, which is a permanent archive and won't move again when future zlib versions are released.

Summary
The WASI build (
install_libpng_wasi.sh) downloads zlib fromhttps://zlib.net/zlib-1.3.1.tar.gz, which now returns 404.zlib.netonly serves the current release at the root path; older versions are moved to the permanent/fossils/archive. zlib 1.3.2 is now current, so the pinned 1.3.1 tarball is no longer at the root.wgetgot the 404 and (by default) wrote no file, so the next step'star xzf zlib-1.3.1.tar.gzfailed — breaking the gocr build.Change
Keeps the pinned
1.3.1version (no dependency change) and points at/fossils/, a permanent archive that won't move again when future zlib versions are released.Verification
