Description

• Add "Auto" recording mode with smart toggle/hold based on press duration

• Attach timestamps to press/release events across hotkey infrastructure

• Update Coordinator: press starts session, release decides latch or stop

• Add unit tests for auto short-tap latching and long-hold ending

• Update frontend types, i18n (5 languages), and UI with new mode option

P2：Auto 模式在快捷键设置页仍显示为 Toggle

openless-all/app/src/pages/settings/ShortcutsSection.tsx:77 仍使用二元判断：

hotkey.mode === 'hold'
  ? t('hotkey.modeHoldSuffix')
  : t('hotkey.modeToggleSuffix')

因此用户在“通用”设置页选择 auto 后，这里仍显示“开始 / 停止”，而上方录音方式显示“自动”；两处文案与实际语义矛盾。项目已经在 openless-all/app/src/lib/hotkey.ts 中集中处理了 auto（并且五种语言都有 hotkey.modeAutoSuffix），请复用该 helper 或补齐完整分支，至少让 auto 显示自动识别。

另外，coordinator.rs 中 hotkey_press_at 的注释仍写着用 elapsed() 判定，当前实现已改为事件时间戳，建议一并更新注释和 PR 描述。

本次复核确认：P1 的事件时间戳已贯穿各平台 adapter、bridge 和 coordinator，released_at - pressed_at 及 take() 清理逻辑正确；最新 CI（Android、Linux、Windows、macOS）均通过。
