Levi Neely 59ee25b010 agent: per-turn and session cost tracking in USD
Usage events now carry a 4th field (costUSD) so OpenRouter's reported
cost flows through unchanged. For backends that only report token counts
(Anthropic, direct OpenAI, Ollama), cost is computed from a prefix-keyed
pricing table. The higher-fidelity source always wins.

Per turn:
- turnInputTokens/turnOutputTokens/turnCostUSD reset before each turn
- recordTurnCost() stores LastTurnCostUSD, adds to SessionCostUSD
- "costLast=$X.XXXX" emitted as an info event at turn end

Session file "cost" returns costLast/costSession key=value pairs.
Agent interface gains Cost() string.
