local-mcp.com: Tool agent_ack was removed.

What changed

Tool agent_ack was removed. Tool agent_sent was removed.

What to do

If your agents call local-mcp.com, pin the new snapshot, patch the affected call sites, and let a green contract check confirm the fix. If you don't use the changed tools, nothing is required, but the rest of the ecosystem just learned about it at the same moment you did.
