// test_suite — smoke tests in-process sobre la API publica de data_table.

// Estos tests NO requieren imgui_test_engine. Solo verifican que las
// estructuras se construyen, los enums son consistentes y los CellRenderer
// configurados producen tablas con `column_specs` validos.
//
// Para tests UI-level con clicks reales: ver fase 2 del issue 0108 con
// imgui_test_engine + FN_BUILD_TESTS=ON.
