feat(xmind): Import relationships as associative lines

[mike-lsadigital]

Summary

• Adds support for importing XMind relationship data as associative lines in SimpleMindMap
• When parsing XMind files, the relationships array is now processed to connect nodes via associative lines
• Relationship titles/labels are preserved and displayed on the associative lines

Background

XMind supports non-hierarchical relationships between nodes (called "relationships"). These are stored in the relationships array in content.json. Previously, SimpleMindMap ignored this data during import.

Changes

Modified simple-mind-map/src/parse/xmind.js:

• Added UUID generation for each node during parsing to enable relationship mapping
• Created maps to track XMind node IDs to SimpleMindMap UIDs
• Process the relationships array to populate associativeLineTargets and associativeLineText on source nodes

Test plan

1. Create an XMind file with relationships between nodes
2. Import the file into SimpleMindMap
3. Verify that the relationships appear as associative lines with their labels

Made with Cursor

代码审查结果

实现了从 XMind relationships 导入关联线的核心逻辑，但 walk 异步未等待与 UID 覆盖风险会导致关系映射不稳定，需要修正后再合并。

✨ 代码亮点

• relationships 导入逻辑与节点映射表设计直观，能够保留关系标题到 associativeLineText
• 对重复 targetUid 做了去重处理，避免重复关联线目标

Caution

🚨 异步递归 walk 未 await，relationships 处理可能早于节点映射完成

walk 被声明为 async，并且内部会调用 handleNodeImageFromXmind（可能向 waitLoadImageList 推入异步任务/依赖 files），但调用处 walk(nodeTree, newTree) 没有 await。随后立刻 await Promise.all(waitLoadImageList) 并处理 data.relationships。这会导致：

1. 节点遍历/映射（xmindIdToUid、uidToNewNode）可能尚未完成就开始处理 relationships，从而丢失关联线；
2. waitLoadImageList 可能在 walk 继续进行时才被 push，Promise.all 可能等待不完整。
   即便当前 walk 内部没有显式 await，也属于易碎实现，后续任何在 walk 内引入 await 都会立刻触发该竞态问题。

建议: 将 walk 的递归调用与根调用都改为 await，保证遍历完成后再等待图片任务、再处理 relationships。
