Pathological Zig packages

Each branch is a separate package that can be fetched using zig fetch to test handling of these cases. URLs:

• https://github.com/ianprime0509/pathological-packages/archive/BRANCH.tar.gz
• git+https://github.com/ianprime0509/pathological-packages#BRANCH

A handy way to test many pathological cases on Linux is to create a FAT32 filesystem, which is case-insensitive and does not support symlinks:

fallocate -l 1G fat32.fs
mkfs.fat -F32 fat32.fs
mkdir fat32.mnt
sudo mount -o rw,umask=0000 fat32.fs fat32.mnt
ZIG_GLOBAL_CACHE_DIR=fat32.mnt zig fetch URL
