Flintmark 0.32.4

• Fresh-open YAML defaults to Properties preview. Notes that start with
  YAML frontmatter now initialize the caret just after the frontmatter block, so
  the Properties panel appears immediately on open while still revealing editable
  YAML when the panel itself is clicked.
• Fix: long documents keep preview stable while fast-scrolling. Live Preview
  decorations no longer rebuild from viewport-only ranges on every scroll; this
  keeps CodeMirror's height map stable for code-heavy notes and prevents the
  temporary source/blank rendering seen when scrolling quickly through long
  documents. Very large files above the full-preview cutoff now keep a stable
  source view instead of attempting partial layout-affecting preview.
