Insert a helper that strips filler-only editor content (stray <br> and caret-anchor text nodes) before inserting reference/annotation chips and on paste, so chips no longer land after an empty line. Also anchor the caret after each inserted/updated chip and reorder focus/insert so the caret reliably follows the new chip.
