Summary

• Add MilvusVectorStoreDriver with Milvus Lite default storage at ./milvus.db plus configurable uri, token, db_name, and consistency_level.
• Create collections with explicit id, vector, text, namespace, and metadata fields, AUTOINDEX vector indexing, and validation for existing collection schema and vector dimensions.
• Support upsert, load, query, delete, namespace filtering, and scalar metadata filters with escaped filter expressions.
• Add the drivers-vector-milvus extra, vector store docs, and a Milvus Lite example.

Hi @collindutter @shhlife, friendly ping for review when you have a chance.

This adds a Milvus vector store driver using the existing driver pattern, with optional dependencies, docs, unit coverage, and Milvus Lite integration coverage. The current checks are green; happy to adjust naming or configuration details to fit the project conventions.
