WIP: Experimental local testing setup with test host app

- Created Xcode project for PeekabooTestHost app - Added test files to explore running tests within app context - Modified bundle ID in LocalOnlyTests to match test host - Added various test runner implementations (XCTest, SimpleTestRunner) - This approach aims to run tests within app bundle for proper permissions
