CommunityToolkit.VectorData.Chroma 1.0.0-preview

[Laurianti]

CommunityToolkit.VectorData.Chroma 1.0.0-preview in place of ChromaDotNet.VectorData 0.4.3.

• The samples and the tests reference CommunityToolkit.VectorData.Chroma 1.0.0-preview from nuget.org.

• The namespace changes. The types and their API stay the same:

  -using ChromaDB.VectorData;
  +using CommunityToolkit.VectorData.Chroma;

• The READMEs link to the new package. The main README says that it is the Chroma provider of the AI Community Toolkit.

Tested:

• dotnet test: 10/10.
• With Ollama and Chroma 1.5.9 in a container:
  • AgentWithMemory_Step10_MemoryUsingChroma_Ollama: the first session writes its memories to Chroma, and the second session recalls them.
  • AgentWithRAG_Step06_ChromaRAG_Ollama, AgentWithRAG_Step07_ChromaBasicTextRAG_Ollama: the answers come from the documents and cite their source.

Not tested: the samples that use Microsoft Foundry (AgentWithMemory_Step10_MemoryUsingChroma, AgentWithRAG_Step06_ChromaRAG, AgentWithRAG_Step07_ChromaBasicTextRAG).
