This PR introduces a new highlighter, `semantic`, tailored for semantic text fields. It extracts the most relevant fragments by scoring nested chunks using the original semantic query. In this initial version, the highlighter returns only the original chunks computed during ingestion. However, this is an implementation detail, and future enhancements could combine multiple chunks to generate the fragments.
