固定 10 节点大关的生成层，但还没有接入主流程

- 新增了 FixedRunNodeSequenceBuilder.cs，现在 Plain 主题会固定生成 1战 2事 3战 4店 5战 6事 7战 8店 9事 10Boss。普通战斗节点的 LinkedLevelId 固定映射为 1 -> 2 -> 3 -> 1，第 10 个 Boss 节点固定绑定 Level 4。 - RunStateFactory.cs 增加了 CreateFixedRun(...)，可以直接创建带 10 节点固定序列的 RunState。RunModel.cs 也补了几个只读查询：NodeCount、GetNodeBySequenceIndex(...)、IsBossNode(...)，方便后面接真实流程。
