Summary of Changes

Hello @geoyee, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

此拉取请求旨在解决当应用遇到无效地理数据时，用户界面可能出现报错或无法编辑修改的问题。通过在关键的数据处理和转换函数（如 bboxAutoFit、transformCoord 和 GeoJSON2Wkt）周围引入 try-catch 错误处理机制，本 PR 显著增强了应用的健壮性。现在，即使输入数据格式不正确或无效，应用也能更优雅地处理这些异常情况，从而提升了整体的用户体验和系统的稳定性。

Highlights

• 错误处理增强: 在 geojson-editor 组件中，为 bboxAutoFit 函数调用添加了 try-catch 块，以防止在处理无效地理数据时界面崩溃，从而提升了应用的稳定性。
• 坐标转换健壮性: 在 layer-list 组件中，为 transformCoord 函数调用添加了 try-catch 块。如果坐标转换失败（例如，由于无效坐标），将清空图层特征，避免界面错误，确保了数据处理的鲁棒性。
• WKT 转换稳定性: 在 wkt-editor 组件中，为 GeoJSON2Wkt 函数调用添加了 try-catch 块，确保在 GeoJSON 到 WKT 转换过程中出现错误时，应用能够优雅地处理，避免了潜在的界面问题。

Code Review

这个 PR 通过在几个关键位置添加 try...catch 块，解决了因无效数据导致界面报错的问题，从而提高了应用的健壮性。在 geojson-editor 和 wkt-editor 中的错误处理是合理的，通过 console.error 记录了异常。然而，在 layer-list 组件中，catch 块是空的，这会静默地吞噬错误，不利于未来的调试。建议在所有 catch 块中都记录错误信息，以保持一致性和可维护性。

[gemini-code-assist]

空的 catch 块会静默地捕获并忽略错误，这是一种不推荐的做法，因为它会隐藏潜在的问题，并给未来的调试带来困难。如果 transformCoord 函数在此处抛出异常，开发人员将无法从控制台看到任何错误信息，从而难以定位问题根源。

建议在这里记录错误，以便于追踪和解决问题。
