Closes #39028 Fixed empty lines appearing when collapsing files with diagnostic messages in the diagnostics panel. Added a flag to track when processing a `FoldedBuffer` and skip `Near/Below` blocks (diagnostic messages) that immediately follow it. This prevents diagnostics from rendering as empty lines when their file is collapsed.
