@rc-component/tree 1.5.3 checkable zero fix @rc-component/select 1.11.0 zero label fix

💡 Result:

These look like version-change notes, but the **`@rc-component/select@1.11.0` release does not list a zero-label fix**—its release note says it fixes option-position announcements in virtual mode. ([github.com](https://github.com/react-component/select/releases?utm_source=openai))

I couldn’t verify from the available release notes what changed in **`@rc-component/tree@1.5.3`** regarding checkable zero values. The package version exists, and its docs describe `checkable` as enabling node checking. ([npmjs.com](https://www.npmjs.com/package/%40rc-component/tree?utm_source=openai))

提升 @rc-component/tree 的最低版本。

@rc-component/tree@1.5.3 使用 if (props.checkable)，并将 checkable 强制转换为 !!checkable。因此 treeCheckable={0} 仍会被当作未启用。src/OptionList.tsx 中的 isReactRenderable 不能修复 Tree 内部的转换。

@rc-component/select@1.11.0 已通过数字分支保留标签 0，无需因该问题提升 Select 版本。将 @rc-component/tree 的最低版本提升到包含零值 checkable 修复的已发布版本。

Review comment at @package.json at line 48:
Update the @rc-component/tree dependency in package.json to a minimum released
version that fixes zero-valued checkable handling; do not change
@rc-component/select, since its numeric-label handling already preserves 0.
