Slack Team HITL — User Input Required (Simple)
===============================================
Simple port of AgentOS human_in_the_loop/team/user_input_required.py.
A team member's tool requires additional user input before it can execute.
The run pauses and Slack shows input fields. The user fills them and submits.
Try in Slack:
@bot plan a vacation for me
Slack scopes: app_mentions:read, assistant:write, chat:write, im:history
