CCO Tools — what your tools really cost

MCP and Agent token costs used to be constants picked once (mcp__* ≈ 200 in, Agent ≈ 500). Real results vary by orders of magnitude — a "list all issues" query and a one-row lookup are the same tool name and nowhere near the same cost. On MCP-heavy sessions the budget meter was guessing at its biggest line item.

CCO now measures every tool result and learns the average per tool name.
