Replace per-keystroke DOM element creation/removal with a persistent off-screen mirror element stored in useRef. The mirror and cursor span are lazily created on first use and reused for all subsequent caret position measurements, eliminating layout thrashing. Cleanup on component unmount removes the element from the DOM. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
