v0.1.2: 宗族气韵（职事/悟道/谱系/碑录/庆典/飞升/音效）

- 职事任命：长老(+修炼)/供奉(+战力)/执事(+坊市)/掌教(+闭关) 每人加成叠加，上限管理
- 功法悟道：修习积悟性点，小成/大成逐级+战力，大境界突破传道于直系晚辈
- 宗族谱系页：世代分带 + 夫妻同卷 + 子孙连枝，点节点开详情，先人簿可查
- 功德碑：宗主辞世即勒石，宗祠页碑录永存
- 百年庆典 + 飞升之路事件链（留世坐镇/仙风入体 或 云游飞升/宗族蒙荫）
- 合成音效（WebAudio）：鼓点/钟鸣/纸韵/磬响，设置页开关
- 单测 29→38；typecheck/build 通过；GUI 冒烟受限于 WSLg 掉线（SMOKE-TIMEOUT 优雅退出）
