Pull request overview

Adds Milvus database selection support to the RAG “simple” MilvusStore so callers can target a specific Milvus database (and optionally create it) instead of always operating on the default DB.

Changes:

• Add databaseName (and optional databaseProperties) to MilvusStore builder and propagate it into Milvus SDK requests.
• Ensure the configured database exists (create if missing) and switch the client to that database during initialization.
• Extend unit tests to cover builder options and database-related initialization paths via mocks.

@LearningGp Thanks for your review! I have submitted the new code, primarily with the following changes:

• Rename database to keep consistent.
• Add unit tests.
• Deprecated the MilvusStore#create method in favor of using Builder instead.
• Set databaseName as default if not defined.

@LearningGp I have updated the java docs, thanks for your review again!
