Return External Tool Execution to Slack

"""
Return External Tool Execution to Slack
=======================================

Pause on a Kubernetes diagnostic the Agent cannot execute. Slack displays the
tool name and command argument, then collects the operator's external result.

Prerequisites: SLACK_TOKEN, SLACK_SIGNING_SECRET, OPENAI_API_KEY
Run: .venvs/demo/bin/python cookbook/05_agent_os/17_slack/hitl_external_execution.py
Try in Slack: Ask "Check api-gateway pods in the production namespace."
Slack scopes: app_mentions:read, assistant:write, chat:write, im:history
