Fix accidental macOS 27 deployment target bump

MACOSX_DEPLOYMENT_TARGET was silently bumped 26.2 -> 27.0 in commit
8451db1, most likely by Xcode beta auto-updating it when the project
was opened/built with the macOS 27 beta SDK. No code in the project
actually requires macOS 27 APIs.

 ## Building
 
-### Build Scripts
-
-| Script | Architecture | Output |
-|--------|-------------|--------|
-| `build.sh` | Apple Silicon (arm64) | Installs directly to `/Applications` |
-| `build-dmg.sh` | Apple Silicon (arm64) | `oAI-<version>-AppleSilicon.dmg` on Desktop |
-| `build-dmg-universal.sh` | Universal (arm64 + x86_64) | `oAI-<version>-Universal.dmg` on Desktop |
-| `build_nb/sv/da/de/en.sh` | Apple Silicon (arm64) | Build + launch in specific language |
-
-All scripts: find Developer ID cert, clean-build via `xcodebuild`, re-sign with `codesign --options runtime --timestamp`, verify. Version is read from `MARKETING_VERSION` in `project.pbxproj`.
