freedakgmail f2cb5e66b2 fix: 退休检测改为按最新合同类型判断,排除劳务协议员工
detectRetirementRisks、updateEmployeesRetirementDays、日历退休日期查询
均改为 include 最新合同并在代码中判断 contractType,而非用 some 查询
(some 会匹配到历史 FIXED 合同导致劳务人员仍被检测)

【改革规则】
- 男性职工:60岁 → 63岁,每4个月延迟1个月
- 女性干部/管理岗:55岁 → 58岁,每4个月延迟1个月
- 女性工人/操作岗:50岁 → 55岁,每2个月延迟1个月
【当前进度】截至${date.getFullYear()}${date.getMonth() + 1}月,改革已实施${monthsElapsed}个月
- 男性当月退休年龄:${BASE_MALE}${maleDelayMonths > 0 ? `+${maleDelayMonths}个月` : ''}
- 女性干部当月退休年龄:${BASE_FEMALE_CADRE}${femaleCadreDelayMonths > 0 ? `+${femaleCadreDelayMonths}个月` : ''}
- 女性工人当月退休年龄:${BASE_FEMALE_WORKER}${femaleWorkerDelayMonths > 0 ? `+${femaleWorkerDelayMonths}个月` : ''}
【个人退休年龄】根据出生年月逐人计算:
达到基准退休年龄的时间点不同,延迟月数也不同。
例如:1965年1月出生的男性,2025年1月满60岁,延迟0个月,60岁退休;1965年5月出生的男性,2025年5月满60岁,延迟1个月,60岁1个月退休。
改革依据:2024年9月13日全国人大常委会《关于实施渐进式延迟法定退休年龄的决定》
过渡期:2025年1月1日至2039年12月31日(15年)`
