  Clarify the relationship with LibreChat and broader use cases

  Why:

  CURRENT

  The primary use case is for integration with LibreChat, but this simple API can be used for any ID-based use case.

  COPY-PASTE FIX

  Copy

  While primarily designed for seamless integration with LibreChat, this robust and simple API is engineered for broad applicability across any ID-based RAG use case, serving as a versatile backend for various applications requiring document indexing and retrieval.
