feat(timeline): 交互式分支演出 + 从任意节点开始 + 时间轴分面板/自适应

Browse Source 
- 交互分支：播到选择/战斗/随机节点暂停，在镜头下方弹按钮手选，点完接对应分支续演
- 从任意节点开始：单击节点选中→「从选中处开始」或双击节点，立即从该处播放；
  起始位置按从开头到该节点途中的走位重放算出(角色站在应有位置)，已离线验证
- 布局分两块(上舞台/下时间轴)，时间轴 playhead 仅播放时居中、暂停可自由滚
- 时间轴自适应宽度按钮(整条压进可视区)+鼠标滚轮横向滚动，解决长时间轴够不着节点
- 演示事件 QY_TLDEMO 扩充两条分支(和解→随机夜晚/拔剑→战斗胜败)，去掉对焦NP1
