The per-agent /stats page shows what the swarm agents board lacked about
turns. The new tab reads the turn count and duration the harness already
records: average duration, cache hit rate, tokens per turn, turns per hour
by agent and by model, duration percentiles, and the wake source and result
mixes. The duration histogram used the SDK default buckets, which stop at
10 s while a turn averages 24 s, so every p95 read a flat 10 s; it now has
explicit bounds up to an hour.
