v0.16.0

## Summary
- Updated model list to support DeepSeek R1 and DeepSeek V3, available on both DeepSeek and SiliconFlow
- GraphRAG enhancements and refactoring: Support KG maintenance over the whole knowledge base dynamically; Support Light and General working mode---entity deduplication and community detection become optional.
- Support for Tagging to improve search quality. You can maintain the tags, and tag the chunks of other knowledge bases, to improve the search relevance.
- Support Iterator operator in Agent.
- Support Research Report Generator in Agent.
- Support for customizing the metadata of chunks, enhancing chunk prompts.
