     * Removes all individual run JSON files from the `pulse-results/` directory

     *
     * When `resetOnEachRun: false`, each run writes its own timestamped JSON to
     * `pulse-results/` and then `_mergeAllRunReports()` merges them all. However,
     * if files from *older* sessions accumulate there (e.g. because a previous run
     * was interrupted before the post-merge cleanup, or because the user ran tests
     * on a previous day), `_getFinalizedResults()` de-duplicates by `test.id` and
     * collapses results from both sessions into a single entry — producing a
     * `totalTests` count lower than the actual number of tests that ran.
     *
     * Cleaning up at `onBegin` time guarantees each run starts with a fresh slate.
