fix: support Android IME mask input

[nrps9909]

Summary

• recover masked input from the native input event when Android virtual keyboards report event.key as Unidentified
• reuse the existing mask-cell formatting path for inserted text and forward/backward deletion
• cover both single and range pickers with Android-style keydown/input sequences

Why

Masked picker input currently relies on keydown to identify numeric keys. Android IMEs such as Gboard and SwiftKey can report Unidentified, so the mask handler ignores the character even though the following native input event contains it.

The fallback is narrowly gated to an immediately preceding Unidentified keydown. Ordinary keyboard input continues through the existing keydown path, avoiding duplicate processing.

Fixes #929.

Validation

• npm test -- --runInBand — 15/15 suites, 470 passed, 2 skipped, 29 snapshots
• focused ESLint for the changed source and test files
• Prettier check and git diff --check
• npm run lint:tsc reaches only the existing deprecated Jest matcher type errors in tests/picker.spec.tsx; the exact base reproduces the same errors

AI assistance disclosure: Codex was used to trace the masked-input event flow, implement the fallback, and draft regression tests. I verified the failure on current master before the fix and ran the validation above on the submitted commit.

Walkthrough

变更概述

Input 组件支持 Android 虚拟键盘的 Unidentified 按键。组件改用原生 input 事件恢复字符和删除操作。新增 DayPicker 与 DayRangePicker 的掩码日期输入测试。

Changes

Android IME 掩码输入

Layer / File(s)	Summary
提取格式化按键处理与状态管理 src/PickerInput/Selector/Input.tsx	组件将按键处理提取为 triggerFormatKey，并记录 Unidentified 按键状态。失焦时重置该状态。
接入原生输入事件并验证日期输入 src/PickerInput/Selector/Input.tsx, tests/keyboard.spec.tsx	组件根据 inputType 和 data 处理字符、Backspace 与 Delete。测试覆盖 DayPicker 和 DayRangePicker 的 YYYYMMDD Android IME 输入。

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 3764e

Android masked-input handling now accepts characters and deletion from native IME events while preserving the existing formatting and validation behavior. Regression coverage is included, and no actionable merge-blocking risk remains beyond normal checks.
