p66: 每日任务目标具体化 TargetNpc/TargetTile 定点

- Kernel Occupation：TaskTargets + targetNpcOf/targetTileOf + dailyTaskOfWith/
  refreshTodayWith/refreshStateWith（splitmix 同源定点，候选排序消除顺序依赖，禁随机）
- 仅既有 satisfiesCompletion 会读目标的模板定点：帮工→TargetNpc、翻土→TargetTile；
  其余 8 模板目标保持 None（不改完成语义）
- Desktop WorldBootstrap：reachableTargets（世界 NPC + 样板菜地瓦片）+
  occupationStateForWorld/refreshOccupationTodayWorld；Game 开局/跨日/证据路径切换
- 历史入口 dailyTaskOf/refreshState/occupationStateFor 保留为空候选通配包装（逐字节不变）
- 红先 P66TaskTargetTests（8 例）：同 seed 幂等、跨 seed 落在可达集合、候选顺序无关、
  历史通配回归、帮工/翻土定点门控完成、跨日重定点、v3 round-trip + v2 基线
- scripts/p66-target-report.fsx + docs/evidence/p66-analysis.txt（PASS）
- Desktop 328/328，Kernel 119/119；digest 953775FA…7F6C ×3 PASS；Sim.fs 未动
