fix(skills): 修复 design-handoff 医生端原型输出质量

- match-tokens: alias 增加值条件映射，支持 doctor/patient variant 自动检测
- parse-prototype: 支持 IosFrame label prop 提取（JSX 属性模式）
- interaction-rules: login-cta 增加 exclude_patterns 避免"立即关注"误报
- tokens.yml: T.pri/T.priL/T.priD alias 改为数组格式，按值匹配 variant

验证: 患者端 T.pri→--tk-pri 确认，医生端 T.pri→--tk-pri.doctor 确认
