feat: support search input autocomplete overrides

[nrps9909]

Summary

• expose autoComplete as a public Select prop and forward it only to the internal search input
• preserve new-password as the default to retain Chromium native-autocomplete suppression
• document the compatibility default and cover both default and explicit off paths

The input remains type="text" with role="combobox", preserving the ARIA correction from #1222. Applications affected by password-manager UI can now opt into autoComplete="off" without a TypeScript error or leaking the attribute onto the Select root, while existing consumers retain the established fallback.

Closes #1249.
Closes #768.

Verification

• exact base 29e9ddac1b8eb3dba4a6681d7c886b542a9d7425: the explicit override regression failed because autoComplete="off" did not reach the input, which still rendered new-password
• focused Select.test.tsx: 110 tests and 5 snapshots passed
• TypeScript passed
• ESLint passed
• Prettier and git diff --check passed
• prior full validation on this branch: 21 suites, 437 tests, 21 snapshots; ESM/CJS output and declarations

The initial revision proposed changing the global default to off. Based on maintainer review and the history in #538/#1222, this revision deliberately retains new-password and narrows the change to an opt-in override.

AI assistance disclosure: Codex was used to trace the input prop flow and prior changes, check for duplicate work, implement the regression coverage, and run the validation. I verified the cited behavior locally against the exact commits.

Walkthrough

Select 为搜索输入框新增可配置的 autoComplete 属性。该属性支持显式传值，并保留 new-password 作为默认值。类型声明、DOM 属性过滤、文档和测试已同步更新。

Changes

Select autoComplete 支持

Layer / File(s)	Summary
autoComplete 属性契约 src/BaseSelect/index.tsx, src/SelectInput/index.tsx	BaseSelectProps 和 SelectInputProps 新增可选的 autoComplete?: string。autoComplete 不会传递到外层 DOM 元素。
搜索输入框属性解析与验证 src/SelectInput/Input.tsx, tests/Select.test.tsx, README.md	搜索输入框优先使用显式 autoComplete，其次使用上下文值，最后使用 new-password。测试验证默认值和 off 值的转发。README 新增属性说明。

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

Merge Risk: ⚪ Minimal · up to 103e4

The PR adds an opt-in autocomplete override for the Select search input while preserving the existing default behavior and keeping the attribute off the Select root. With the documented tests and validation passing, no actionable merge-blocking risk remains.

Linked Issues check	⚠️ Warning	PR 满足 issue [#768] 的要求：为 Select 增加类型化的 autoComplete 属性，并仅转发到内部搜索输入框。但根据变更摘要，未提供值时仍回退到 "new-password"，README 也记录该默认值。这未满足 issue [#1249] 关于避免使用密码相关 autocomplete 值的主要要求。	将默认 autocomplete 值从 "new-password" 改为 "off"，并同步更新 Input 逻辑、README 和测试，确保显式传入的 autoComplete 值仍只应用于内部搜索输入框。
