Vendor OpenClaw source as Adolf fork baseline

Adolf is a fork/vendored clone of github.com/openclaw/openclaw (v2026.6.11),
free to diverge. Tree copied sans upstream .git; upstream remote added for
future syncs. Node pinned to 24 (.nvmrc); engines already require >=22.19.
Preserves docs/ARCHITECTURE.md.

+title: Subagent handoff
+
+scenario:
+  id: subagent-handoff
+  surface: subagents
+  coverage:
+    primary:
+      - agents.subagents
+  objective: Verify the agent can delegate a bounded task to a subagent and fold the result back into the main thread.
+  successCriteria:
+    - Agent launches a bounded subagent task.
+    - Subagent result is acknowledged in the main flow.
+    - Final answer attributes delegated work clearly.
