feat: 集成豆包 ASR 语音识别后端，支持 /voice doubao 切换

[claude-code-best]

• 新增 src/services/doubaoSTT.ts 适配模块，将 doubaoime-asr 的 AsyncGenerator 协议适配为现有 VoiceStreamConnection 接口
• /voice doubao 启用豆包后端，/voice 使用默认 Anthropic 后端
• 后端选择持久化到 settings.json 的 voiceProvider 字段
• 豆包后端跳过 Anthropic OAuth 认证、语言限制和 Focus Mode
• 豆包后端松手即出结果，跳过 processing 状态
• 凭证文件存放在 ~/.claude/tts/doubao/credentials.json
• doubaoime-asr 作为 optionalDependencies 安装
• 移除 /voice 命令的 claude-ai 可用性限制，所有用户可用

📝 Walkthrough

Walkthrough

This PR adds Doubao ASR as an optional voice provider alongside Anthropic: new Doubao streaming adapter, settings schema for provider selection, command/hook changes to route between providers, optional dependency and gitignore update, and documentation updates reflecting dual-backend voice mode.

Changes

Cohort / File(s)	Summary
Config & Dependencies /.gitignore, package.json	Adds credentials.json to .gitignore and adds doubaoime-asr as an optionalDependencies entry.
Doubao ASR Adapter src/services/doubaoSTT.ts	New streaming adapter: dynamic imports doubaoime-asr, provides isDoubaoAvailable()/isDoubaoAvailableSync(), connectDoubaoStream() with AsyncGenerator-based streaming, transcript/error/c lifecycle handling, and re-exports FinalizeSource.
Voice Command src/commands/voice/index.ts, src/commands/voice/voice.ts	Command metadata updated (description, removes availability), uses isVoiceAvailable() for enabled/hidden checks, accepts optional args to select provider, switches/stores voiceProvider, runs Anthropic auth checks only when selecting Anthropic, and tailors post-enable messaging/behavior per provider.
Voice Hooks & Runtime src/hooks/useVoice.ts, src/hooks/useVoiceEnabled.ts	Provider-aware logic: routes connect calls to connectDoubaoStream vs connectVoiceStream, skips keyterm fetch for Doubao, uses Doubao synchronous availability in some flows, and branches enablement/auth checks based on settings.voiceProvider. Adds internal isDoubaoProvider() helper.
Settings & Feature Flags src/utils/settings/types.ts, src/voice/voiceModeEnabled.ts	Adds optional `voiceProvider: 'anthropic'
Docs & README README.md, docs/features/voice-mode.md	Updates Voice Mode docs and README to document Doubao backend, credentials, usage (/voice doubao), architecture changes, and acknowledgements.
Tests src/utils/suggestions/__tests__/commandSuggestions.test.ts	Minor test typing change: cast helpers to as unknown as Command.

Poem

🐰 A Doubao hops into the stream,
Two voices now to chase the dream,
Settings set, the choice is clear,
Streams whisper—near and near,
Rabbit cheers: record and gleam! 🎤✨
