Add a robust Java assert removal transformer to convert generated unit tests into regression tests. This removes assertion statements while preserving function calls, enabling behavioral verification by comparing outputs between original and optimized code. Key features: - Support for JUnit 5 assertions (assertEquals, assertTrue, assertThrows, etc.) - Support for JUnit 4 assertions (org.junit.Assert.*) - Support for AssertJ fluent assertions (assertThat().isEqualTo()) - Support for TestNG and Hamcrest assertions - Framework auto-detection from imports - Handles assertAll grouped assertions - Preserves non-assertion code (setup, Mockito mocks, etc.) - 57 comprehensive tests with exact string equality assertions Co-Authored-By: Claude Opus 4.5 <[email protected]>
The log statement was using `func_name` which is only defined in the Java block, not the JavaScript block. Co-Authored-By: Claude Opus 4.5 <[email protected]>

Summary
Add a robust Java assert removal transformer to convert AI-generated unit tests into regression tests. This removes assertion statements while preserving function calls, enabling behavioral verification by comparing outputs between original and optimized code.
