Proves that a plugin installed from the gareth-skills marketplace actually loaded and can be invoked. Does nothing except print one known phrase. Use when Gareth says "roundtrip check", "/roundtrip-check", "prove the marketplace works", "did the plugin install", or "test the marketplace round trip". Purely diagnostic. It reads nothing, writes nothing, and runs no commands.
