Two strategies to improve content hit rate when the right document is found:
1. Small notes (<=2000 chars): return full content_snippet as matched_chunk
so the answer is always present for correctly-retrieved small notes
2. Large notes: return top-3 chunks by similarity joined with \n---\n
instead of just the single best chunk (~2700 chars vs ~900 chars)
Also raises CONTENT_DISPLAY_LIMIT from 250 to 2000 for richer FTS results.
