Reusable agent templates, a library of execution strategies, and parallel agent teams with quality gates

Notes & tips

• Await the run. AgentTeam.run and execute are async.
• Start from templates. get_all_templates() is the cheapest way to see what a team can be built from.
• get_strategy takes a registry name, not a class.
• AgentTeam is fan-out + gate, not a planner — you pick the agents and the gates.
