agentapi 0.2.2, screen support

Is it OK to add the flag like this or do we need to check the cli
version to determine whether the new flag is available? Or I could just
throw in an `||` to run the command again without the flag if it fails.

Blocked on adding AgentAPI to Claude.

Will need to do the same for Goose.
