fix(ma-dict-select): 修复 slot 透传并支持自定义 option 渲染

[westng]

• 影响范围: web/src/components/ma-dict-picker/ma-dict-select.vue
• 类型: 修复（兼容增强）

变更概述

• 修复 slot 透传问题：遍历 Object.keys($slots)，过滤 default 与 optionDefault，将其余具名插槽原样透传到内部 el-select。
• 支持自定义选项渲染：新增 optionDefault 插槽，分组与普通选项均可自定义渲染。
• 保持兼容：未提供自定义插槽时，延用原有 label/i18n 渲染逻辑。

变更前的问题

• 外部具名插槽（如 prefix、empty 等）无法在内部 el-select 生效。
• 选项行无法统一便捷地进行自定义渲染。

变更后的行为

• 所有非默认具名插槽会自动转发到 el-select，prefix、empty、loading 等可正常使用。
• 通过 optionDefault 插槽可统一自定义选项节点（兼容分组与普通项）。

使用示例

{
      label: '业绩分类',
      prop: 'performance_id',
      render: () => MaDictSelect,
      renderProps: {
        dictName: 'PERF_TYPE',
        // multiple: true,
        clearable: true,
        placeholder: t('form.pleaseInput', { msg: '业绩分类' }),
      },
      renderSlots: {
        optionDefault: ({ option }: { option: any }) => {
          // 自定义显示方式
          return `${option.label} (${option.value})`
        },
        label: ({ label, value }: { label: string, value: any }) => {
          return `${label} (${value})`
        },
      },
    },

Summary by CodeRabbit

• 新功能

  • 动态命名插槽现支持每个插槽的作用域数据（slot props），可在自定义插槽内容中访问当前项信息，默认与 optionDefault 插槽行为保持兼容。

• 改进

  • 渲染更可预测、更新更稳定，便于基于插槽内容进行精细化定制。

📝 Walkthrough

Walkthrough

在 ma-dict-select.vue 中，动态命名插槽的渲染改为为每个插槽生成并传递独立的 slotProps（通过 #[slot]="slotProps" 和内部 <slot :name="slot" v-bind="slotProps">），并在 v-for 中直接排除 default/optionDefault 并为模板项添加 :key。

        C-->>S: 使用 slotProps 渲染内容

我在字典林里跳一跳，耳朵竖得高
每个插槽分颗豆，slotProps 全带好
名字一喊就到齐，默认静静绕
数据轻轻递过去，渲染笑得俏
胡萝卜编译通过，前端更欢畅 🥕🐇

Tip

👮 Agentic pre-merge checks are now available in preview!

Pro plan users can now enable pre-merge checks in their settings to enforce checklists before merging PRs.

• Built-in checks – Quickly apply ready-made checks to enforce title conventions, require pull request descriptions that follow templates, validate linked issues for compliance, and more.
• Custom agentic checks – Define your own rules using CodeRabbit’s advanced agentic capabilities to enforce organization-specific policies and workflows. For example, you can instruct CodeRabbit’s agent to verify that API documentation is updated whenever API schema files are modified in a PR. Note: Upto 5 custom checks are currently allowed during the preview period. Pricing for this feature will be announced in a few weeks.

Please see the documentation for more information.

Example:

reviews:
  pre_merge_checks:
    custom_checks:
      - name: "Undocumented Breaking Changes"
        mode: "warning"
        instructions: |
          Pass/fail criteria: All breaking changes to public APIs, CLI flags, environment variables, configuration keys, database schemas, or HTTP/GraphQL endpoints must be documented in the "Breaking Change" section of the PR description and in CHANGELOG.md. Exclude purely internal or private changes (e.g., code not exported from package entry points or explicitly marked as internal).
