Issue Building on macOS 26.5 due to Zig 0.15 Incompatibility

[JLO64]

The Issue

When attempting to build fancy cat via zig build --release=small using Zig 0.15.2 installed via zigup it failed with a bunch of of "undefined symbol" errors because Zig 0.15's bundled system libraries don't recognize macOS 26.5's SDK.

The Fix

As it turns out, Zig 0.15 on Homebrew has a patch for this and installing it via the following commands fixes this issue:

brew install zig@0.15
brew link zig@0.15
rm -rf ~/.cache/zig

Documentation

I'm typing this up primarily in case others run into this issue as well. I'd suggest updating the README's requirements section for users using macOS 26.5 and above and am willing to submit a PR, I just wanted to ask here first before doing so.

Issue #117 is a duplicate of this that I accidentally posted using my non-personal account.

Hi, thank you for opening this issue. You can create a PR for this if you want. One day, when I find the time, I will update the Zig version. I assume this will fix the issue, but the changes needed to update from v15.2.0 to v16.0.0 are not trivial.
