Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly improves the reliability of the Myers diff algorithm implementation by introducing comprehensive fuzz tests. These tests are designed to uncover subtle bugs and edge cases that traditional unit tests might miss, thereby strengthening the algorithm's robustness. The changes also integrate these new tests into the existing build and CI workflows, ensuring continuous validation of the diff package.

Highlights

• Fuzz Testing: Introduced fuzz tests for the diff/myers package to enhance its correctness and identify edge cases.
• Build System Integration: Updated the Makefile and hack/do.sh script to include and run the newly added fuzz tests.

Code Review

This pull request introduces fuzz tests for the Myers diff algorithm, which is a great addition for ensuring correctness and robustness. The changes to the Makefile and hack/do.sh script to support running fuzz tests are well-implemented.

My review focuses on the new test file diff/myers/fuzz_test.go. I've identified a couple of opportunities to improve the test code's maintainability and debugging experience by refactoring duplicated logic and using a standard testing helper feature. Overall, the implementation of the fuzz test is solid.
