…uments This PR fixes the Google GenAI document embedder to not modify input Documents in place when setting embeddings. Instead of mutating the original documents: doc.embedding = embeddings We now create new document instances using dataclass replace: replace(doc, embedding=embeddings) This follows the established pattern from haystack-ai/haystack#9693 and aligns with other integrations (FastEmbed, Optimum, Nvidia, Bedrock, Cohere). Related to: deepset-ai#2174
