💡 What: Optimized loadBaseline in lib/src/core/baseline_manager.dart to cache file modification times asynchronously before sorting them.

🎯 Why: The previous code called statSync() synchronously within the .sort() comparator. Because sorting algorithms evaluate comparators O(N log N) times, this caused unnecessary and repeated synchronous file I/O operations, blocking the Dart event loop and slowing down baseline resolution.

📊 Impact: Reduces synchronous blocking disk operations from O(N log N) to 0, converting it to O(N) asynchronous file checks. This ensures fast execution even with many baseline files.

🔬 Measurement: Verified that all 162+ sate_ai tests continue to pass. The baseline manager accurately identifies the most recently modified baseline JSON file in an optimized manner.

Replaces repeated synchronous `statSync()` disk I/O operations inside a list `.sort()` comparator with a single asynchronous pass that caches the modification times. This transforms an O(N log N) disk access bottleneck into an O(N) async setup, drastically improving file sorting performance in directories with multiple baselines.

The CI build failed because the `fllama` dependency requires a `minSdkVersion` of at least 23, while the example app defaulted to `flutter.minSdkVersion` (which is 21). This caused an AndroidManifest merger error. Updating `minSdk` to 23 in the example app's `build.gradle.kts` resolves the CI build failure.

Resolves CI build failures caused by Android manifest merger errors. The `fllama` dependency requires a `minSdkVersion` of at least 23, but the example app was defaulting to `flutter.minSdkVersion` (which is 21 in this setup). Explicitly setting `minSdk` to 23 fixes the issue.
