perf(asr): speed up local Flow dictation and land CLM/keyboard refactor

Reduce perceived latency from key release to final text: - Adaptive chunking: 2.5s first chunk + 5s follow-ups so short utterances start on-device recognition while still recording. - Session-level ASR warmup and audio-format cache reuse to remove per-utterance cold-start of SpeechAnalyzer. - Mirror live pipelined partials to the keyboard transcript line via a new flow.transcriptionPartial App Group key + Darwin ping. Also commits the accumulated custom language model, Flow session, keyboard extension restructure, and Xiaomi MiMo provider work in progress on this branch.

 ### Added
+- **Xiaomi MiMo cloud provider**: preset for the cloud engine with `mimo-v2.5` polish via `api.xiaomimimo.com` (on-device ASR, same pipeline as other online providers). / **小米 MiMo 云端引擎**：云端引擎新增预设，经 `api.xiaomimimo.com` 使用 `mimo-v2.5` 润色（端侧 ASR，与其他在线服务相同管线）。

+### Changed
+- **Flow ASR pipelining**: shorter first chunk (2.5s) and 5s follow-ups so short utterances start on-device recognition while still recording; session-level ASR warmup and format cache reuse; live partials mirrored to the keyboard transcript line. / **Flow ASR 流水线**：首块 2.5 秒、后续 5 秒，短句录音期间即开始端侧识别；会话级 ASR 预热与格式缓存复用；实时 partial 同步到键盘转写行。

+
+### Added
+- **Custom ASR language model**: on-device `SFCustomLanguageModelData` bias model (computer/IT terms + curated AI/tech brands) prepared via `CustomLanguageModelManager` and applied to `DictationTranscriber` for Chinese dictation; compiled LM/Vocab shared through the App Group. / **自定义语音识别语言模型**：端侧 `SFCustomLanguageModelData` 偏置模型（计算机术语 + 精选 AI/科技品牌词），通过 `CustomLanguageModelManager` 在设备上准备并挂载到 `DictationTranscriber` 用于中文听写；编译后的 LM/Vocab 经 App Group 共享。
 - **Cursor navigation**: keyboard drag pad (`CursorDragPad` / `CursorNavigation`) for precise caret movement. / **光标导航**：键盘拖动手势区（`CursorDragPad` / `CursorNavigation`），精确移动光标。
 - **Key sound feedback**: `KeyboardSoundFeedback` plays system key clicks on input. / **按键音反馈**：`KeyboardSoundFeedback` 在输入时播放系统按键音。
 - **Personal dictionary tooling**: `DictionaryAliasGenerator` and `PersonalDictionaryEntrySheet` for managing custom terms and aliases. / **个人词库工具**：`DictionaryAliasGenerator` 与 `PersonalDictionaryEntrySheet`，用于管理自定义词条与别名。

-// TranslationChip.swift
-// OSGKeyboard · Keyboard Extension
-//
-// Compact chip rendered to the right of `LocaleChip` on the keyboard
-// top bar. Doubles as both the on/off switch and the target-language
-// picker — same Menu pattern as `LocaleChip` so muscle memory transfers.
-//
-// v0.2.1 follow-up: removed the explicit on/off toggle entry. The
-// chip is now a pure picker over the 11 catalog rows (off + 10
-// locales); selecting "不翻译" turns translation off, selecting any
-// locale turns it on with that target. `translationEnabled` is
-// derived from the locale id so the chip / pipeline read the same
-// source of truth.
-//
-// v0.2.1 final review: dropped the "needs cloud" warning state —
-// both engines now run the translate-and-polish step (the local
-// engine routes through DeepSeek via
-// `ProviderConfig.localModeProviderId`). The chip is therefore just
-// off / on, with the same accent treatment either way.
-//
-// Visual states:
-//   • off             → dim outline, "翻译" chip label (menu first row = "不翻译")
-//   • on (any engine) → accent fill, "→ EN" / "→ 日本語" style label
-//
-// Stays in the same visual family as `CloudEngineChip` / `LocaleChip`
-// (Capsule + 28 pt min height + 6 pt vertical padding) so the top bar
-// doesn't grow when translation is enabled.

-//
-// As of v0.2.0 the only on-device backend is iOS 26 `SpeechAnalyzer`
-// + `DictationTranscriber`. The previous Qwen3-CoreML backend has
-// been removed: that path required a ~1.6 GB CoreML bundle, a local

-// (download manager, warm-up service, model registry). We now keep the
-// local engine narrow — same iOS ASR the cloud engine already uses —
-// and let users opt into a cloud polish step after the transcript is
-// produced if they need stronger accuracy on noisy audio or dialectal
-// Chinese. See `LocalPolishConfig` for the post-ASR polish toggle.
-//
-// Why an enum in `Shared` rather than a `Bool`: the value must remain
-// serialisable into the App Group store (so the keyboard extension can
-// observe the selection) and exposed via `ProviderConfig` (UI binding).
-// Keeping the type stable even with a single case avoids a migration
