feat(0.1.16-P1): 资源闭环引擎（修为耗草/炼丹概率化/铸器/灵脉收益/NPC战力/灾变落效）+ C13C14

【A 经济闭环】
- 修为经济化：练气以上修行者月耗灵草（闭关2普通1），无草速修0.6~1.0衰减+缺草年告警
- 炼丹等级化：bonusOf 表达式引擎（白名单安全求值），craftChance 转正；丹方单源 PILL_RECIPES（聚气L1/凝元L2/破境L3）+ 失败折半退料
- 炼器筑宝：FORGE_RECIPES（法器/灵器/法宝，灵矿+兽核+灵石）
- 秘境灵脉：secretQiOf→rollWarbooty 收益门槛（0.5~1.3折算）；掉落按秘境 techGrades 过滤
- NPC 实力参战：raid 强度/风险随 npc.power 浮动（0.5~1.8）
- 灾年落效：疫病/兽潮一次性袭击 + CALAMITY_FAMILY 月度减产乘子

【C 治理】
- C13 破境丹渡劫修正：大境界时药力→tribBoost 加成（+12%）入渡劫事件，不再跳过三选
- C14 存储防线：loadState 补 migrate；MigrationError（TOO_NEW/未知版本）提示升级

【UI 半批】
- 坊市新增 定制tab（丹方/铸器）；ChroniclePanel 手写史书输入条；MemberModal 册立家主钮
- 年报摘要（要闻5条+辞世讣告）；EventModal 选项收益预览
- 结盟引擎：setAlliance（relation≥40）/盟友岁差不降/年利15灵石
