T10: following the current match takes one pass: a forward walk maps matches to cells, line ends are found once; the same occurrence ranks by an identical line, then one grown or cut at its end, then by line and column; a cleared or trimmed history moves no line; the title replays on CursorBlinkingChange, which a reset sends in the parser's order, synchronized updates too, and the tap's reset count is gone
