📝 WalkthroughWalkthroughThis PR adds three new test suites to increase code coverage: catalog_coverage_tests for Catalog module operations, transaction_coverage_tests for concurrent locking and rollback scenarios, and utils_coverage_tests for Value and RpcClient edge cases. Updates CMakeLists.txt to register these test targets. Changes

tests/utils_coverage_tests.cpp (1)
86-96: Test covers connection failure paths well, but consider potential flakiness.The test uses port 1 which is typically privileged and closed, but network behavior can vary across environments. If CI runs in containers with different network configurations, this test might behave unexpectedly. Consider adding a comment documenting this assumption, or using a mock/stub approach for more deterministic testing.

78-135: Good rollback coverage, but cleanup could be more robust.The test correctly exercises the undo log paths for INSERT, UPDATE (with old_rid), and DELETE operations, verifying that
tm.abort()properly reverses all changes.Consider using a test fixture with
SetUp/TearDownto ensure cleanup runs even if assertions fail:♻️ Suggested improvement for robust cleanup

Ensure the fixture exposes the symbols used in the test (tm, txn, table, disk_manager, bpm) so the existing test body can be reused unchanged.
