Pull Request Overview
This PR adds an integration test to verify buildless recovery functionality for Java lambda expressions. The test ensures that CodeQL can properly extract and analyze lambda expressions even when Java compilation fails due to missing imports.
- Creates a new integration test specifically for lambda expression buildless recovery
- Tests unused variable detection in various lambda expression scenarios
- Verifies the extraction errors are handled appropriately during buildless mode
