Sol lead + 16 cheap Luna planners nears all-Sol team results at 70% less cost

The team-scaling installment of the multi-agent experiments: instead of letting the lead size its own team, researchers gave a Sol lead 2, 4, 8, or 16 cheap Luna workers at each workflow stage (planning, implementation, verification).

Findings:

Planning kept adding reward as the team grew: each planner explores a different part of the program
Implementation and verification plateaued at four workers: extra coders just split code into thinner slices for the lead to stitch
16 Luna planners hit 61.8%, near the 63.2% of an all-Sol team that delegates every stage, at $155 vs $510
Near-frontier results at 70% less cost
