* feat: add SeekDB vector database support for knowledge bases
This commit adds complete integration of OceanBase's SeekDB as a vector
database option for LangBot's knowledge base feature.
## Changes
### Core Implementation
- Add SeekDB adapter implementing VectorDatabase interface
- Support both embedded and server deployment modes
- HNSW indexing with cosine similarity
- Async operations with error handling
- Comprehensive logging
### System Integration
- Register SeekDB in VectorDBManager
- Add pyseekdb>=0.1.0 dependency
- Add SeekDB configuration template
- Update README with vector database section
### Documentation
- Complete integration guide with platform compatibility warnings
- Configuration examples for all deployment modes
- Troubleshooting guide for common issues
- Code examples demonstrating usage patterns
- Comprehensive test reports and status documentation
## Testing
Architecture validated end-to-end using ChromaDB:
- File upload → parsing → chunking → embedding → storage
- 828 bytes → 3 chunks → 3 vectors stored successfully
- BGE-M3 model (384 dimensions)
- Status: Completed ✅
## Platform Compatibility
### Embedded Mode
- ✅ Linux: Fully supported
- ❌ macOS: Not supported (pylibseekdb is Linux-only)
- ❌ Windows: Not supported (pylibseekdb is Linux-only)
### Server Mode
- ✅ Linux: Fully supported
- ⚠️ macOS: Known issue (oceanbase/seekdb#36)
- ⚠️ Windows: Untested
### Remote Connection
- ✅ All platforms supported
## Known Issues
macOS Docker server mode affected by upstream bug:
https://github.com/oceanbase/seekdb/issues/36
Workaround: Use ChromaDB/Qdrant or connect to remote SeekDB server.

* chore: remove unused docs
* feature: minimal seekdb change (#1866)
* feat: add SeekDB embedding requester and configuration
This commit introduces a new SeekDB embedding requester, which utilizes the local embedding function from pyseekdb. It includes the necessary Python implementation and a corresponding YAML configuration file for integration. Additionally, a new SVG icon for SeekDB is added to enhance the visual representation in the UI.
* fix: update EmbeddingForm to conditionally render URL field based on model provider
This commit modifies the EmbeddingForm component to conditionally display the URL input field only when the current model provider is not 'seekdb-embedding'. Additionally, it updates the condition for rendering the API key field to exclude both 'ollama-chat' and 'seekdb-embedding' providers.
* chore: update Python version requirement in pyproject.toml to support Python 3.11
* fix: add config default value, when it makes fronted not show spec
* fix: seekdb.py clean metadata. change api
* fix: enhance error handling in SeekDB embedding initialization
This commit adds improved error handling to the SeekDB embedding function. It ensures that a RuntimeError is raised if the embedding function fails to initialize, and wraps the embedding call in a try-except block to catch and raise a RequesterError with a descriptive message in case of failure.
* refactor: update SeekDB database management to use AdminClient
This commit refactors the SeekDB database management logic to utilize the AdminClient for database operations. It replaces the previous temp_client with admin_client for listing and creating databases, ensuring a more robust interaction with the SeekDB API.
* refactor: update SeekDB embedding model initialization to use task manager
This commit refactors the SeekDB embedding model initialization by replacing the direct asyncio task creation with the task manager's create_task method. This change enhances task management and provides a clearer naming convention for the embedding model initialization task.
* perf: integration
* chore: remove unnecessary files
* fix: linter errors

* Expanded WeCom message parsing to capture msgtype, inline voice/video/file/link data, bounded base64 downloads, and richer mixed-message attachments (src/langbot/libs/wecom_ai_bot_api/api.py); added event accessors for new fields (src/langbot/libs/wecom_ai_bot_api/wecombotevent.py).
Converter now maps richer WeCom payloads (text, images, files, voice, video, links) into platform message chain with fallbacks when nothing parsable is present (src/langbot/pkg/platform/sources/wecombot.py).
Preprocessor now turns voice inputs into file URLs for downstream runners (src/langbot/pkg/pipeline/preproc/preproc.py).
Dify runner uploads all incoming files (images/audio/video/docs) after downloading or decoding data URLs, infers MIME types, and passes typed file descriptors into chat/workflow calls (src/langbot/pkg/provider/runners/difysvapi.py).
* Update src/langbot/pkg/platform/sources/wecombot.py
Fixed the issue of duplicate text in the comments.

* feat(platform): add skip_pipeline parameter for webhook responses
Add support for skip_pipeline parameter in webhook responses, allowing
webhook targets to instruct LangBot to skip pipeline processing for
specific messages. When a webhook responds with skip_pipeline=true,
the message is treated as a notification only and bypasses the query pool.
Changes:
- webhook_pusher.py: Parse JSON responses and return skip_pipeline flag
- botmgr.py: Check skip_pipeline before adding messages to query pool
- docker-compose.yaml: Add DNS configuration to fix container networking
