The dashboard's row IS the team now: each listed session folds its WHOLE
subagent subtree into itself (all levels, mirroring the Context tab's cost
fold) — subagent-origin sessions never list, so nothing counts twice. The
session card's billed tokens and priced cost (now labeled 团队用量 /
团队费用), the KPI band's volume and spend, the last-7-days usage chart,
and the heatmap all read the family scope: the subtree's cost buckets
merge per row, the daily ledgers merge day by day, and the composition
split proportions each member's OWN composition instead of the root's.
