login command should be set

Error message

login command should be set

What it means

Guard in conversation_view.rs expecting the agent's login command to be configured when handling the node-runtime resolution path. Fires if the ACP agent server descriptor lacks a login command, which the surrounding code assumes is present by this point.

Solutions

1. Ensure the agent server extension defines a login command
2. Check that agent metadata was fully loaded before rendering the conversation view
