feat(story-simulation): 草稿导出 + 时间线角色点击 + 动作短语优化

1. 草稿导出MD：story-draft-view新增导出按钮，导出完整故事草稿为MD到.qmai/simulations/exports/
2. 草稿导出工具：新增draft-export.ts，支持导出带章节结构的Markdown
3. 时间线角色可点击：SimulatingTimelinePanel支持onInterviewAgent回调，actorName和targetName可点击
4. 新增actionTypePhraseOnly函数：在目标名可点击场景下，返回不含目标名的动作短语
5. 仿真过程中不支持采访：仿真阶段lastSimulationStateRef尚未构建完成，不传递onInterviewAgent避免错误
6. 报告页角色点击采访：上轮已实现，本轮保持不变
