Address PR review comments and fix compiler warnings

- Use XCTAssertEqual with NSNumber cast instead of isEqual+XCTAssertTrue
  for better type safety and failure messages in integration tests
- Add explicit AnyClass? type annotation to suppress type inference warning
- Suppress performSelector leak warnings with pragma for dynamic dispatch
- Replace deprecated Branch.trackingDisabled with preferenceHelper instance
