Master landed the tool-subagent depth budget while this branch was in flight: the numeric default maxDepth now fails the mount against the ACP provider's depthLimit: false, so the composition fixture must state maxDepth: 'provider-managed' — the documented opt-out for a provider whose recursion budget lives in the child harness. The fixture also moves off the retired stdio-demo REPL onto the current app-boot driver pattern (runLoaderSmoke + one-shot cli), and the split isDirectory statements gain the file-not-a-directory case the single-expression form used to cover implicitly.
