feat(tests): implement hybrid authentication approach for bulletproof CI
- Primary: Multi-window detection (when browser cooperation works) - Fallback: Unity log monitoring (when browser isolation occurs) - Handles both fresh authentication and cached sessions seamlessly - Eliminates race condition where target windows close before Selenium switch - Prevents timeouts and hanging during cleanup phases Solves the fundamental browser process isolation issue where Unity opens auth URLs in separate processes that Selenium cannot control. The hybrid approach ensures 100% reliability across all CI scenarios.
