GestureDetector was fighting with IconButton's inner Tooltip gesture
recognizer — onLongPressStart was never called (only vibration from
tooltip). Replaced with Listener (raw pointer events) + manual 500ms
Timer, which bypasses the gesture arena entirely.

New VoiceMicButton widget (press-and-hold to record, release to send):
- Records audio to a temp .m4a file via the `record` package
- Slide-up gesture cancels recording without sending
- Pulsing red mic icon + "松开发送/松开取消" feedback during recording
New flow for voice messages:
1. Temp "🎤 识别中..." bubble shown immediately
2. Audio uploaded to POST /api/v1/agent/sessions/:id/voice-message
(multipart/form-data; backend runs Whisper STT)
3. Placeholder replaced with real transcript
4. WS stream subscribed via new subscribeExistingTask() to receive
agent's streaming response — same pipeline as text chat
Voice messages act as async interrupts: if the agent is mid-task the
backend hard-cancels it before processing the new voice command,
so whoever presses the mic button always takes priority.
Files changed:
chat_remote_datasource.dart — sendVoiceMessage() multipart upload
chat_repository.dart — subscribeExistingTask() interface method
chat_repository_impl.dart — implement subscribeExistingTask(); fix
sendVoiceMessage() stub
chat_providers.dart — ChatNotifier.sendVoiceMessage()
voice_mic_button.dart — NEW press-and-hold recording widget
chat_page.dart — mic button added to input area

Voice sessions set systemPrompt to the voice-mode instruction string,
causing every voice conversation to display '你正在通过语音与用户实时对话。请…'
as its title in the chat history list.
Title derivation priority (highest to lowest):
1. metadata.title — explicit title saved by backend on first task
2. metadata.voiceMode == true → '语音对话 M/D HH:mm'
3. Fallback → '对话 M/D HH:mm' based on session createdAt
- Remove redundant "从剪贴板粘贴" option from attachment menu (long-press to paste natively)
- Remove super_clipboard dependency (no longer needed)
- Fix timeline vertical line overlapping icon nodes by using dynamic dotRadius
- Dim input field placeholder color to AppColors.textMuted

Two major features in this commit:
1. Streaming Markdown Rendering Optimization
- Replace deprecated flutter_markdown with gpt_markdown (active, AI-optimized)
- Real-time markdown rendering during streaming (was showing raw syntax)
- Solid block cursor (█) instead of AnimationController blink
- 80ms token throttle buffer reducing rebuilds from per-token to ~12.5/sec
- RepaintBoundary isolation for markdown widget repaints
- StreamTextWidget simplified from StatefulWidget to StatelessWidget
2. Multimodal Image Input (camera + gallery + display)
- Flutter: image_picker for gallery/camera, base64 encoding, attachment
preview strip with delete, thumbnails in sent messages
- Data layer: List<String>? → List<Map<String, dynamic>>? for structured
attachment payloads through datasource/repository/usecase
- ChatAttachment model with base64Data, mediaType, fileName
- ChatMessage entity + ChatMessageModel both support attachments field
- Backend DTO, Entity (JSONB), Controller, ConversationContextService
all extended to receive, store, and reconstruct Anthropic image
content blocks in loadContext()
- Claude API engine skips duplicate user message when history already
ends with multimodal content blocks
- NestJS body parser limit raised to 10MB for base64 image payloads
- Android CAMERA permission added to manifest
- Image.memory uses cacheWidth/cacheHeight for memory efficiency
- Max 5 images per message enforced in UI
Data flow:
ImagePicker → base64Encode → ChatAttachment → POST body →
DB (JSONB) → loadContext → Anthropic image content blocks → Claude API

Three root causes fixed:
1. TimelineEventNode: Replaced IntrinsicHeight (which forces intrinsic
height calculation on unbounded content) with CustomPaint-based
_TimelineLinePainter that draws vertical lines based on actual
rendered widget size. Also added maxLines/ellipsis to label text
and mainAxisSize.min on inner Column.
2. ApprovalActionCard: Changed countdown + action buttons layout from
Row with Spacer (which requires infinite width) to Wrap with
spacing, preventing horizontal overflow on narrow screens.
3. AnimatedCrossFade in _CollapsibleCodeBlock and _CollapsibleThinking:
Wrapped with ClipRect and added sizeCurve: Curves.easeInOut to
prevent the outgoing child from extending beyond parent bounds
during the cross-fade transition.

Implement DB-based conversation message storage (engine-agnostic) that
works across both Claude API and Agent SDK engines. Add ChatGPT/Claude-style
conversation history drawer in Flutter with date-grouped session list,
session switching, and new chat functionality.
Backend: entity, repository, context service, migration 004, session/message
API endpoints. Flutter: ConversationDrawer, sessionId flow from backend
response via SessionInfoEvent, session list/switch/delete support.

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)
