feat(world): 首潜创世时刻与世界数据回路闭合（宪法P1第五批）

- 世界数据回路：深潜完成→plantCoral（此前无调用方，珊瑚/地层/活力数据自此真实生长），动态import防循环依赖
- useFirstDiveStore：首潜全部完成触发创世版签名时刻（宪法第三条§5）
- SignatureMoment 增加 genesis 变体：「第一颗星，亮了——从这次首潜开始，这个世界开始记住你」
- WorldConditions + RitualComplete 接线：仪式收尾展示「今日海况」一句话世界叙事（宪法第六条，仪式成为世界的每日开场），焦虑防线措辞，留存关闭时隐去
