+Execution Modes ~

+The I/O view supports two execution modes:
+
+Combined Mode (default: :CP run)
+    • Single execution with all test inputs concatenated
+    • Matches platform behavior (e.g. Codeforces multi-test format)
+    • Shows one verdict for the entire execution
+    • Input split: All test inputs concatenated
+    • Output split: Single program output + verdict
+
+Individual Mode (:CP run all / :CP run n / :CP run n,m,...)
+    • Separate execution for each test case
+    • Per-test verdicts for debugging
+    • Input split: Selected test inputs concatenated
+    • Output split: All test outputs concatenated + per-test verdicts
