/// ClideTestApp — standalone test harness for platform integration.

/// Launched via `make run-testmode`. Runs a table of exec tests against
/// external binaries, prints results to stdout (captured by the make
/// target), then exits after 15 seconds. Add test cases here whenever
/// you need to isolate a platform issue without the full app.
