What the agents cost, as an opt-in setting

Obeya now counts what every agent costs and can show it: on each card beside its conversation, in a project's sheet with each workstream's share, and for the whole canvas in the bar, where a click lists the cards that cost the most. The figures stay hidden until "Costs" is turned on under Configuration → General, so the interface stays as calm as before for everyone who doesn't need them. Counting goes on while they're hidden, so turning them on later shows the full cost from the start. Claude Code's figures are its own estimate at API list prices; Codex's tokens are priced at OpenAI's list prices.
