Updated the macOS GitHub Actions workflow to build both architectures (build-macos-arm64 + build-macos-x86_64), then package a universal app by passing both binaries into osx/makebundle.sh.
Documented the universal build invocation in osx/DEBUGGING.md so local builds can reproduce Intel + Apple Silicon compatibility packaging.
suppressed noisy defaults read failures for missing preference keys,
fixed unsafe/empty test expressions that caused test: argument expected,
corrected the gettext app domain from APP=name to APP=zoitechat.
Improved launcher behavior for architecture mismatches (Bad CPU type in executable) by detecting exit 126 and printing a clear hint plus file output for ZoiteChat-bin.
Updated osx/makebundle.sh so bundling is more Intel/Apple Silicon friendly:
dynamically resolves/writes prefix and prefix:enchant (Homebrew Intel vs Apple Silicon layouts),
still adapts enchant data path (share/enchant vs share/enchant-2),
prints bundled binary architecture after bundling so mismatches are immediately visible.
Extended macOS debugging docs with a dedicated “Bad CPU type in executable” section and explicit Intel (x86_64) build commands.
