hailin b7814d42a9 fix: resolve 3 timeline UI bugs (blank start, spinner style, tool status) 
1. 任务开始时空白状态：当 agent streaming 启动但尚无 assistant
   响应时，在时间线末尾插入虚拟 "处理中..." 节点（带脉动 * 动画），
   避免用户发送 prompt 后界面无任何反馈。
   (chat_page.dart: _needsWorkingNode + ListView itemCount+1)

2. * 动画从旋转改为脉动：_SpinnerDot 由 Transform.rotate 改为
   Transform.scale（0.6x↔1.2x 缩放 + 透明度 0.6↔1.0 呼吸），
   duration 从 1000ms 降至 800ms 并启用 reverse，视觉效果类似
   星星闪烁而非机械旋转。
   (timeline_event_node.dart: _SpinnerDotState)

3. 工具执行完成后状态卡在 spinner：ToolResultEvent 到达时仅创建
   新 toolResult 消息，未回溯更新对应 toolUse 消息的 ToolStatus，
   导致时间线上工具节点永远显示 executing spinner。修复：在
   ToolResultEvent handler 中向前查找最近的 executing 状态的
   toolUse 消息，将其 status 更新为 completed/error。
   (chat_providers.dart: ToolResultEvent case)

hailin 20325a84bd feat: redesign chat UI from bubble style to timeline workflow 
Replace traditional chat bubble layout with a Claude Code-inspired
timeline/workflow design:
- Vertical gray line connecting sequential event nodes
- Colored dots for each event (green=done, red=error, yellow=warning)
- Animated spinning asterisk (*) on active nodes
- Streaming text with blinking cursor in timeline nodes
- Tool execution shown as code blocks within timeline
- User prompts as distinct nodes with person icon

New file: timeline_event_node.dart (TimelineEventNode, CodeBlock)
Rewritten: chat_page.dart (timeline layout, no more bubbles)

hailin dfc541b571 feat: add Markdown rendering and phone-call voice entry to chat UI 
Chat message rendering:
- MessageBubble: replace plain SelectableText with MarkdownBody for
  assistant messages, with full dark-theme stylesheet (headers, code
  blocks, tables, blockquotes, list bullets)
- StreamTextWidget: render completed messages as MarkdownBody, keep
  plain-text + blinking cursor for actively streaming messages

Voice interaction redesign:
- Remove all long-press-to-record code (~100 lines): AudioRecorder,
  SpeechEnhancer, mic pulse animation, voice indicator bar,
  SingleTickerProviderStateMixin
- Add phone-call button in AppBar (Icons.call) that navigates to the
  existing AgentCallPage for full-duplex voice conversation
- Add prominent "语音通话" entry button on empty chat state
- AgentCallPage was already fully implemented (ringing → connecting →
  active → ended, dual-direction WebSocket audio, GTCRN denoise,
  Kokoro TTS playback, waveform visualization) but previously unused

hailin 1075a6b265 refactor: 重构 chat_page 对接完整架构，集成全部 stream event widget 
## 问题
chat_page.dart 包含内联的简化版 ChatMessage/ChatState/ChatNotifier（约180行），
绕过了已实现的完整 Clean Architecture 层：
- domain/entities/chat_message.dart（含 ToolExecution、ApprovalRequest）
- domain/entities/stream_event.dart（9种 sealed class 事件）
- chat_providers.dart（完整 ChatNotifier 支持审批/工具/常驻指令）
- 5 个独立 widget 全部闲置未使用

## 变更
1. 删除内联重复代码（~180行）：ChatRole、ChatContentType、内联 ChatMessage、
   内联 ChatState、内联 ChatNotifier、chatMessagesProvider
2. 切换到正式 chatProvider（chat_providers.dart），支持全部 9 种 StreamEvent
3. 集成 5 个已有 widget：
   - MessageBubble — 用户/AI 消息气泡（带时间戳）
   - StreamTextWidget — AI 流式回复动画光标
   - ToolExecutionCard — 工具执行详情（名称/输入/输出/状态/风险等级）
   - ApprovalActionCard — 审批卡片（倒计时/通过/拒绝/过期处理）
   - AgentThinkingIndicator — 思考动画指示器
4. 新增 _AgentStatusBar — 实时状态条（思考中/执行中/等待审批）
5. 新增 _StandingOrderDraftCard — 常驻指令草案渲染
6. AppBar + 输入区添加停止按钮，审批等待时显示提示
7. 消息渲染按 MessageType 分发：text/thinking/toolUse/toolResult/approval/standingOrderDraft

3. 导航图标添加 outlined/filled 选中态区分
4. 设置页重构为大厂风格（圆角图标分组 + 主题底部弹窗选择）

hailin a568558585 feat: replace speech_to_text with GTCRN ML noise reduction + backend STT 
Replace traditional on-device speech_to_text with a modern pipeline:
- Record audio via `record` package with hardware noise suppression
- Apply GTCRN neural denoising (sherpa-onnx, ICASSP 2024, 48K params)
- Trim silence, POST to backend /voice/transcribe (faster-whisper)

Changes:
- Add /transcribe endpoint to voice-service for audio file upload
- Add SpeechEnhancer wrapper for sherpa-onnx GTCRN model (523KB)
- Rewrite chat_page.dart voice input: record → denoise → transcribe
- Keep NoiseReducer.trimSilence for silence removal only
- Upgrade record to v6.2.0, add sherpa_onnx, path_provider
