-# Examples:
-#   make test-e2e                              # Run all tests
-#   make test-e2e TEST_PATTERN=Test_GS         # Run gang scheduling tests
-#   make test-e2e TEST_PATTERN=Test_GS1        # Run specific test
-#   make test-e2e TEST_PATTERN=Test_TAS        # Run topology tests
-#   make test-e2e DIAG_DIR=e2e-diagnostics     # Output diagnostics to specific directory
-#   make test-e2e DIAG_MODE=both               # Output to stdout and file
-#   make test-e2e DIAG_MODE=stdout             # Output to stdout only

-# Variables:
-#   TEST_PATTERN - Test name pattern to match (optional)
-#   DIAG_DIR     - Directory for diagnostic files (default: operator/)
