darkrun-version

name	darkrun-version
description	Show the running darkrun engine version, plugin version, build kind (compiled bundle vs dev source), runtime, and entry point — for triaging behavior that doesn't match the docs

Call darkrun_version_info and report what it returns — engine version, plugin version, build kind (compiled vs dev), runtime, and entry point. Mention any pending update. When the build kind is dev, note that engine-source edits are live only after a rebuild (cargo build) — there's no hot reload.
