feat(v2): add recursive subagent cost aggregation in agent store and pane

Browse source 
getTotalCost() recursively aggregates costUsd, inputTokens, outputTokens
across parent and all child sessions. AgentPane done-bar displays total
cost in yellow when children are present and total exceeds parent cost.
