  Reposition README's opening to clarify RAG optimization

  原因：

  当前

  For many applications, encoding a whole text document into a single embedding representation is not useful. Many applications require retrieving smaller parts of the text and dense vector-based information retrieval systems often perform better with smaller text segments because of the limited information capacity of embedding vectors.

  This repository provides the code and research for **Late Chunking (or chunked pooling)**, an advanced strategy to optimize Retrieval Augmented Generation (RAG) systems. Unlike traditional static text chunking, late chunking improves RAG performance by dynamically processing retrieved documents just before LLM inference, especially when relevant information spans multiple text chunks.
