feat(v0.4): 回响编年史 — 跨周目叙事时间轴系统

- 新增 ChronicleEntry / RunStartSnapshot 类型与 GameState 字段
- 新建 chronicle.ts: 5 纪元名生成、模板化叙事、里程碑检测、run delta 计算
- engine.ts performPrestige 构建编年史条目并重置 runStart
- gameStore: init 兼容旧存档 + tickTide 记录星潮 + resolveCurrentNode 计 BOSS 击杀
- chooseConstellationPerk 回填最近一条 entry 的 perksThisAscension
- 新建 ChronicleDialog.tsx: 时间轴 UI + 5 纪元循环色 + 入场动画
- 新增 6 项成就: 首部编年/三纪元回响/五纪元闭环/首杀维度/维度猎手/星潮亲历者
- 新增 chronicle / chronicleOpen 程序化音效
- 修复关键 BUG: PrestigeDialog disabled 逻辑错误导致玩家永远无法飞升
- 修复 UX: newBp=0 时不再永久禁用飞升按钮（v0.3.1 星图+v0.4 编年史已提供动机）
