Performance

• Block-level diff optimization: ~229x faster for large JSON arrays (50K lines: 39s → 171ms)
  • Detects indent-based block boundaries in formatted JSON
  • Compares segment hashes (~10K) instead of individual lines (~130K)
  • Only runs line-level diff on changed segments
  • Falls back to full line diff for non-array structures
  • Adds 50K-line guard for fallback path (full REPLACE)
