refactor: use shared renderability and value guards

[QDyanbing]

说明

• 使用 isNonNullable 替换 combobox value 与 suffix icon 的本地非空判断
• 使用 isReactRenderable 统一 clear icon 的 fallback 与渲染逻辑，支持数字 0
• 移除重复的本地 hasValue helper，并将 @rc-component/util 最低版本提升到 ^1.13.0

验证

• npm run tsc
• npm run lint
• npm test -- tests/Select.test.tsx --runInBand

Summary by CodeRabbit

• 改进
  • 优化清除图标的显示判断，支持数字 0 等可渲染内容作为清除图标。
  • 当配置或传入的清除图标不可渲染时，自动使用备用图标。
  • 优化组合框模式下搜索值与选中值的同步处理。
  • 优化前缀、后缀及相关内容的渲染判断，确保数字等可渲染内容正常显示，并避免显示不可渲染内容。

Walkthrough

本次变更升级 @rc-component/util。选择器使用统一的非空值判断和 React 可渲染值判断。hasValue 工具函数被移除。测试覆盖数字 0 的清除图标、前缀和后缀。

Changes

选择器值与图标处理

Layer / File(s)	Summary
统一非空值判断 package.json, src/BaseSelect/index.tsx, src/Select.tsx, src/utils/commonUtil.ts	将 @rc-component/util 更新至 ^1.13.0。BaseSelect 和 Select 使用 isNonNullable。Select 移除 hasValue，commonUtil 移除该函数。
清除图标与前后缀渲染 src/SelectInput/index.tsx, src/hooks/useAllowClear.tsx, src/SelectInput/Affix.tsx, tests/Select.test.tsx, tests/Multiple.test.tsx	使用 isReactRenderable 处理清除图标、前缀和后缀。不可渲染的清除图标回退为 '×'。测试验证数字 0 可渲染，以及 false、空字符串、null 和 undefined 不渲染。

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 677ef

Select now consistently renders numeric zero for clear icons and prefix/suffix affixes while omitting non-renderable values. The covered behavior and passing checks show no current merge-blocking risk.

Poem

小兔更新工具箱，
非空判断更统一。
数字零也能成图标，
前缀后缀清晰现。
选择器通过新测试。

CI failed.

已补充 clearIcon={0} 的组件测试并推送 7296b1b。当前 Codecov patch、Codecov project 和 test workflow 均已通过。剩余的 Vercel 失败为 Authorization required to deploy，需要 React Component 团队成员授权，不是代码或测试失败。

[yoyo837]

The migration is incomplete for numeric-zero affixes.

Both prefix and suffix eventually pass through src/SelectInput/Affix.tsx, which still returns null for !children. Therefore prefix={0} and suffix={0} are still dropped. For a zero suffix, BaseSelect can also add the -show-arrow class while no affix is rendered, leaving CSS state and DOM output inconsistent.

Please update Affix to use isReactRenderable(children) and add coverage for numeric zero plus the false/empty/nullish fallback cases. The current clear-icon changes and the ^1.13.0 dependency update otherwise look reasonable.

[QDyanbing]

Addressed in 677efee. Affix now uses isReactRenderable(children), with integration coverage for numeric-zero prefix/suffix values and the false, empty-string, and nullish boundaries. The full test suite (443 tests), TypeScript, and coverage checks pass locally.

[yoyo837]

Affix now renders numeric-zero children, with integration coverage for the affix and clear-icon boundaries, and the coverage gates are green again. LGTM.
