Simplify CI tests: use swift test directly

Removed xcodebuild test execution which was hanging due to app
initialization and potential UI dialogs. Now using Swift Package
Manager tests directly which:

- Avoids code signing requirements completely
- Runs faster without building the full app
- Tests all packages (main, AXorcist, DesignSystem)
- Doesn't require a running app instance

This should finally allow tests to run successfully in CI.
