Title: 🐛 [Bug]: After deleting a component from the canvas, the component-related styles are not automatically deleted.

[chilingling]

这里没有支持自动删除的特性，主要是考虑到：

1. 如果有多个组件同时使用了该样式，关联删除该样式会导致其他组件的样式被丢失。
2. 如果该组件样式关联的样式有多个状态（:hover、:active 等等），是否同样级联删除，是否有其他组件关联了这些级联状态的样式？
3. 如果用户只是想删除了该组件，然后添加一个新组件，重新应用刚刚已经编排好的样式，自动删除关联的样式也是不符合需求的。

综合以上的考虑，估短期内不做自动删除的特性。

There is no feature to support automatic deletion, mainly due to:

1. If multiple components use this style at the same time, deleting the style will cause the styles of other components to be lost.
2. If the styles associated with this component style have multiple states (:hover, :active, etc.), will they also be deleted in cascade? Are there other components associated with the styles of these cascade states?
3. If the user just wants to delete the component, then add a new component, and re-apply the style that has just been arranged, automatically deleting the associated style does not meet the needs.

Based on the above considerations, it is estimated that automatic deletion will not be implemented in the short term.
