Invalid xcodebuild argument fix

[cursor]

Add validation for xcodebuild extraArgs to prevent failures from invalid options.

The xcodebuild command fails when users pass unrecognized options like -test-arg via extraArgs. This PR introduces a validation step that checks for such invalid arguments and provides a clear error message, guiding users to use the testRunnerEnv parameter for passing environment variables to the test runner instead.

Note

Adds a guard to prevent invalid xcodebuild flags that cause test runs to fail.

• Introduces utils/xcodebuild-validation.ts with validateXcodebuildExtraArgs to detect invalid options (e.g., -test-arg) and return a clear, actionable error pointing to testRunnerEnv
• Integrates validation into test_device, test_macos, and test_sim logic before invoking xcodebuild
• Adds unit tests: utils/__tests__/xcodebuild-validation.test.ts and new validation cases in simulator/__tests__/test_sim.test.ts (exporting test_simLogic, using createMockExecutor)
