refactor(0.1.14-P1): 内核归位——game/ 按引擎架构重排（零行为漂移）

结构（旧 game/core+engine → 新 engine/ 域）：
- engine/kernel/  时钟/随机/插件协议/fxqueue/timesense/format/urgency/guide/names（原 core）
- engine/narrative/  legacy/报告/列传/谱系/年轴（原 core 叙事族）
- engine/runtime/   World/creation/pcgen/ApiFacade/capabilities/pluginManager/boot/clocks + Systems/*（12 系统）
- engine/sim/     Market（未来 WorldSim 同行）
- 旧 game/core、engine/systems、engine/world.ts 等路径全部废弃（无 re-export 兼容层）

验证：35 套件/967 测试全绿（金钟罩三档零漂移=纯搬迁无行为变化）
