- 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

- Add super_clipboard and file_picker dependencies
- Clipboard paste: reads PNG/JPEG image data from system clipboard
- Multi-image: pickMultiImage with remaining count limit
- File picker: supports images (jpg/png/gif/webp) and PDF files
- Updated attachment preview to show file icon for non-image types

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

Root cause: PcmPlayer called openPlayer() without audio session config,
so Android defaulted to earpiece-only mode. When the mic was actively
recording, playback was silently suppressed — the agent's TTS audio was
sent successfully over WebSocket but never reached the speaker.
Changes:
1. PcmPlayer (pcm_player.dart):
- Added audio_session package for proper audio session management
- Configure AudioSession with playAndRecord category so mic + speaker
work simultaneously
- Set voiceCommunication usage to enable Android hardware AEC (echo
cancellation) — prevents feedback loops when speaker is active
- defaultToSpeaker routes output to loudspeaker instead of earpiece
- Restored setSpeakerOn() method stub (used by UI toggle)
2. AgentCallPage (agent_call_page.dart):
- Fixed fire-and-forget bug: _pcmPlayer.feed() returns Future but was
called without await, causing interleaved feedUint8FromStream calls
- Added _feedChain serializer to guarantee sequential audio feeding
3. Dependencies:
- Added audio_session package to pubspec.yaml

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
