v0.1.5

Changed

• Improved wrapped long-line viewer performance by caching rendered visual row
  chunks and prewarming nearby chunks without reducing syntax highlight
  correctness.
• Added lightweight wrap and XML-like highlight checkpoints for huge logical
  lines, so repeated deep scrolling rebuilds from nearby state instead of the
  start of the line.
• Optimized tail-page calculation and rendering for jumps near huge wrapped
  lines while keeping the last full page visible.
• Clamped wrapped EOF row offsets to the actual final full page instead of
  preserving overscrolled partial pages.
• Fixed End/G in wrap mode so single-line long records jump to the real
  final visual page and report 100% at EOF.
• Added wrapped-line position feedback with +N rows status text and subtle
  continuation gutter ticks for very long repeated records.
• Reduced large-record indexing overhead by scanning formatted output in fixed
  byte buffers instead of allocating per physical line during index creation.
• Added an ignored release-mode performance smoke test for huge wrapped-line
  rendering and last-line jump paths.
