test(cache): 修复CacheConfigTest边界值测试
- 修改 shouldVerifyCacheManager_withMaximumIntegerTtl 为 shouldVerifyCacheManager_withMaximumAllowedTtl - 使用正确的最大TTL值（10080分钟，7天）而不是 Integer.MAX_VALUE - 新增 shouldThrowException_whenTtlExceedsMaximum 测试验证边界检查 - 所有1266个测试用例通过 - 覆盖率: 指令81.89%, 行88.48%, 分支51.55% docs: 添加项目状态报告 - 生成 PROJECT_STATUS_REPORT.md 详细记录项目当前状态 - 包含质量指标、已完成功能、待办事项和技术债务
