The rv tool needs automated testing to catch regressions and verify correct functionality across different usage scenarios. Add selftests that validate monitor listing (including containers and nested monitors), monitor execution with different configurations (reactors, verbose output, tracing), and trace output format for both per-task and per-cpu monitors. Error handling paths are also tested. Tests use a shared engine for common patterns.
