Subject: [PATCH] refactor(build): optimize JVM memory allocation and enable
 parallel test execution

- Increase JVM heap memory from 512m to 2-4G for faster test execution
- Add G1GC garbage collector and tiered compilation for improved performance
- Enable parallel test execution with threadCount=4 to avoid shared state issues
- Add incremental recompilation mode and Zinc server for faster builds
- Increase Scala compiler JVM memory from 64m/1024m to 512m/2G
- Add language feature flags to suppress compiler warnings
- Add test-results directory to .gitignore for cleaner repository
- Apply optimizations consistently across obp-api, obp-commons, and root pom.xml
- These changes reduce build and test execution time while maintaining stability
