Replace who hosts an AI SDR's meetings (by sid): the sender profile itself (kept whatever the list says; its link is the agent's link to offer) and colleagues by team member sid or free name, each with their own booking link, how the reply introduces them, and the scenarios they host (a key hosted once; a scenario nobody names is the sender's). Read the agent first and send the whole list back: a row left out is gone. No calendar and no booking: the reply sends the host's link as the Rules say.

Contract:

• MCP tool update_agent_hosts, registry package mcp.unibox/agents, mount unibox.agent.
• Operation update, response envelope update.
• Flags: none.
