fix: avoid duplicate search tags for grouped options

[dvd233]

In tags mode, searching for an exact match inside an option group adds a second temporary option because the search checks only top-level options. Apply the existing value and filter-field checks to group children while preserving group matches, custom field names, and disabled-option handling.

Closes #795.

Validation:

• Added 13 regression/control cases. The six bug cases fail on the unmodified base with two rows instead of one.
• Full rc-test --runInBand --coverage: 21 suites, 456 tests, and 21 snapshots passed.
• pnpm run lint: 0 errors, 38 warnings. pnpm run compile: ESM, CJS, declarations, and Less passed.
• 13 real Chromium scenarios with React 18.3.1 passed, including grouped/legacy options, custom fields, free text, label/value differences, and disabled options.

pnpm run tsc reports seven existing Jest matcher-alias type errors. The same seven errors occur on the unmodified base under the identical dependency lock; the library declaration build above passes.

Summary by CodeRabbit

• 问题修复
  • 标签模式下，搜索值匹配分组选项的父级或子项时，会选择已有选项，不再创建重复的临时标签。
  • 自定义过滤隐藏分组选项时，仍可通过 Enter 选择未禁用项；禁用项不会触发选择变更。
• 测试
  • 补充分组标签模式下的匹配、过滤与键盘选择测试。

Title check		标题准确概括了主要变更：修复分组选项在 tags 模式下生成重复搜索标签的问题。表述简洁、明确，并与代码和测试变更一致。
Linked Issues check		直接关联的开放 issue #795 要求 tags 模式在 OptGroup 子项值与搜索值完全相同时，不显示重复的临时选项。src/Select.tsx 现在检查 mergedFieldNames.value、配置的 optionFilterProp，并递归检查分组的 mergedFieldNames.options 子项。匹配父级或子项时，代码返回现有过滤结果，不创建临时选项…
Out of Scope Changes check		变更集中在 src/Select.tsx 的 tags 模式临时选项判断，以及 tests/Tags.test.tsx 的相关回归和控制测试。分组子项、值字段、optionFilterProp 和禁用选项处理都直接支持 issue #795 的目标。没有证据表明存在与该目标无关的源代码或测试变更。

_{我是兔子，轻敲回车键，
分组选项，逐项来相见。
搜索值对上，标签不重添，
禁用选项静静留在原点。
胡萝卜旁，测试也圆满。}
