v1.18.4

Fixed

• Scroll math is now in visual rows, not logical lines. 1.18.3 fixed
  the scroll-time line reveal for soft-broken paragraphs but the bug
  survived for single source lines that were themselves wider than the
  viewport — exactly what happens in documents with prose paragraphs
  written as one long physical line (common in note-taking tools).
  User reproduction: a 180-char line at source line 105 in
  personal_notes.md wrapped visually but block.height() still
  returned 1, so scrolling past it shifted the following table by the
  missing rows.

  The fix moves the entire coordinate system to visual rows:

  • DocBlock::height() now returns wrapped visual-row counts for
    Text blocks (via a new visual_height: Cell<u32>), recomputed on
    every layout-width change by update_text_visual_heights.
  • scroll_offset, cursor_line, total_lines, and the visual
    selection range are all in visual rows. j / k move by one
    visual row, matching pager conventions (less, bat) rather than
    strict vim logical-line semantics.
  • Text blocks render via Paragraph::new(full_text).scroll((N, 0))
    instead of slicing by logical line, so ratatui's wrap and our
    scroll math agree on what's visible.
  • recompute_positions translates logical-in-block link and anchor
    indices to absolute visual rows so the f link picker and TOC
    jumps still land on the right row under wrapping.
  • collect_match_lines records matches in visual rows so n / N
    doc-search navigation jumps don't drift when wrapped paragraphs
    sit between matches.
  • source_line_at and logical_line_at_source gain width-aware
    variants (_width) used everywhere that converts between cursor
    position and source-line number (edit mode entry, yy / visual
    yank, link-picker line filtering).

  Gutter line numbers now track logical source lines (with blank
  continuation rows) rather than absolute visual rows, so long
  paragraphs show a single number on the first wrap row and blanks
  below — the correspondence users expect from an editor/pager.
