Key changes:
- Renamed AppHost project and updated all references across test files
- Added new BackPressure.Runner project with build automation for the Flink IR Runner JAR
- Enhanced error handling and test robustness with retry mechanisms and extended timeouts

This code block duplicates the JobBuilder chain from lines 38-43. Consider extracting this into a private method to eliminate code duplication and improve maintainability.

The macOS detection logic is implicit (else clause). Consider adding explicit $IsMacOS check for better clarity and maintainability.

Using string.IndexOf in a loop for counting occurrences is inefficient. Consider using a more efficient approach like splitting or regex counting for better performance, especially with large JSON payloads.

1. Added Java and Maven installation to Gateway's Dockerfile 2. Updated Gateway build process to include building the Java project 3. Simplified LocalTesting to have a single test with a basic flow 4. Set up test environment with 1 Kafka, 1 FlinkDotnet, 1 Flink JobManager, and 1 Flink TaskManager 5. Implemented multiple FlinkDotnet jobs covering all implementations 6. Updated .gitignore to exclude generated JAR files
