Compress openai-codex-desktop with maximum zstd

The build image sets COMPRESSZST to zstd's default level, which leaves this
1.3 GB Electron tree at 448 MB -- larger than the 334 MB deb it repackages.
Maximum zstd brings it to 323 MB, beating xz on both size and decompression
speed, for ~4 extra minutes of build time.

Carried as an .omarchy patch so it survives AUR syncs. pkgrel picks up the
Omarchy suffix accordingly.
