WHY IT NEEDS A POLICY

Why teammate_spawn_team needs a policy

The tool creates a new team entity, which is a reversible write operation. It spawns a collaborative group of agents, which could have downstream resource implications, but the primary action is creation/configuration rather than execution of arbitrary code, destruction of data, or financial commitment.
