Function build_agent_for_reload 

pub fn build_agent_for_reload(
    world: &mut World,
    tool_service: &CliToolService,
    config: &Config,
    shared_mcp: Arc<Mutex<ToolExecutor>>,
    mcp_tool_defs: &[Tool],
    hub: &InteractionHub,

    subagent_tx: UnboundedSender<SubAgentOp>,
) -> Result<Entity, String>

Like build_agent, but skips the required-at-spawn region gate - used by restart recovery, which reloads a run that already passed the gate when first spawned and whose context window is restored from a snapshot after this call.
