- 在 pricingService 中硬编码 1 小时缓存价格（Opus: $30/MTok, Sonnet: $6/MTok, Haiku: $1.6/MTok） - 更新 usage 捕获逻辑以分别记录 ephemeral_5m 和 ephemeral_1h 缓存 tokens - 改进费用计算逻辑，正确计算两种缓存类型的费用 - 新增 recordUsageWithDetails 方法支持详细的缓存数据 - 保持向后兼容性，支持旧的数据格式 - 删除测试脚本 test-openai-refresh.js - 修复 OpenAI token 刷新逻辑 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
