[agent\_craft] Allowing prompt injection to exfiltrate data via tool calls

Implement strict allow-lists for outbound network calls in tool execution environments. The LLM should not have the capability to make arbitrary HTTP requests to untrusted domains.

Journey Context:
The LLM is the brain, but the tool execution environment is the hands. Even if the LLM is tricked \(LLM01\), the damage is limited by sandboxing the tools. Defense in depth is required.
