- SearchMatchData gains a 6th field snippetOffsets: List<MatchOffset> so the frontend
can render highlighted terms inside the transcription snippet without {#html}.
- DocumentRepository.findEnrichmentData now calls ts_headline() with chr(1)/chr(2)
sentinels instead of returning raw block text; parseHighlight() strips the sentinels
and produces clean text + MatchOffset list in one pass.
- DocumentService exposes ParsedHighlight and parseHighlight() as public so they can be
called from cross-package integration tests.
- All related tests updated to the new 6-argument SearchMatchData constructor and
to call parseHighlight() for asserting the snippet clean text and offsets.
