chore: Refactor getHeadingText to remove title parameter (#1707)

getHeadingText passes the current accumulated title as the recursion's second parameter and then concatenates the returned string back onto title:
title += child.value
title += getHeadingText(child.children, title)
Because the recursive call receives the already-accumulated title, the recursive result itself includes that prefix, so the outer concatenation duplicates earlier text (e.g. "A" + "AB" -> "AAB").
