Introduce an automated, global execution summary printed at the absolute tail of the test run: 1. Track counts mid-flight inside the print_test_result() accumulator, clearly separating pass counts into standalone main tests vs. individual subtests (where num_test_cases > 1). 2. Accumulate the precise descriptions of all failed test cases directly into a global string buffer, formatted with their suite indices (e.g., 3.1: Parse event definition strings) for effortless cross-referencing. 3. Define a summary printer function print_tests_summary() that emits a colored outline of the final pass, skip, and fail totals, followed by the explicit list of failed tests. 4. Invoke the summary printer right before freeing the test array at the absolute tail of __cmd_test(), guaranteeing that the summary is successfully printed even if an internal emergency signal cleanup occurs or if the user interrupts the run early.
