docs(algorithm): 画像层设计 v2 — 时间语义/Feature Registry/RFM 八象限/圈人群

画像从'被动打分+话术标签'升级为有治理、有时间语义、可圈人群的特征体系:
- 时间语义模型(snapshot/window/lifetime/trend,每特征声明;画像=压缩当前态,历史留fact层,版本流=point-in-time)
- Feature Registry 单一收口(OneModel)+ CI 防漂移
- persona_features 加 typed value JSONB(支持 SQL 圈人群)
- RFM 八象限(统一现有 value+risk:M→value,R+F→lifecycle/risk)+ 召回语义映射
- lifecycle_stage 生命周期分层;treatment_chain 移出画像→episode 视图
- Campaign 圈人群→批量召回;质量监控;分 5 PR 实施
