Open-source AI agent framework fixes silent auth failures for sub-agents

A bug in the OpenClaw system caused sub-agents to fail silently because they were not provided with authentication tokens. The issue stemmed from the main agent being instructed to copy its token into every tool call, a process that did not extend to sub-agents spawned through sessions. This meant sub-agents, like Dalí, were unable to authenticate their requests, leading to silent failures. The fix involves using a `before_tool_call` hook to inject the necessary authentication token directly from the host, rather than relying on the language model to reproduce it, thus ensuring consistent authentication for all agents.
