Sentence-transformers wrapper

sentence_transformer_embeddings.py defines SentenceTransformersEmbeddings, a LangChain Embeddings implementation backed by HuggingFace sentence-transformers. It is a local port adapted from LangChain's HuggingFace partner package, kept here to avoid the dependency issues that came with routing through ollama.

utils.py holds the supporting helpers.

World entities such as buildings, terrain, and utensils serialize to LangChain documents in the entities package; these embeddings turn that text into vectors for retrieval, configured through the vector search params.
