v0.1.5: 人物志（志向/渡劫/列传/契合/回声）

- 志向系统：七向（求道/镇族/承宗/商略/兵略/耕读/云游）成年礼自动定志，
  量化加成入修炼/战力/坊市/灵田/添丁/声望，云游减修但际遇更频
- 大境界渡劫：炼气→筑基起，晋升改走劫难事件三选——硬渡/请护法(100灵石)/
  压制来年；护法失败或受牵连；渡劫成败与心性、气血挂勾，高阶有小陨落率
- 灵根本命契合：功法元素×主灵根，契合者修炼+6%/战力+4%，详情页「本命」徽章
- 人物列传：自动列传生成器（生平/修行脉络/历险/姻缘/子嗣/大比/墓志铭），
  成员详情小传分页 + 春秋原列传长卷
- 四邻回声：每两年一桩——友好赠礼/敌视暗桩/中立传闻三态动态事件
- 修复：回声事件 npcId 解析错误、事件优先级（惯例>传闻）
- 测试 176→197（志向加成/契合/渡劫三轨/压制通道/列传结构/回声三态）
