Whiteboard: zoom bar and dot grid, layers panel, appear motion, sound cues, focus rings
and AccessKit labels; .draw files with legacy .excalidraw still readable;
notescraft-cli export whiteboard.
Security: export.pdf and file.export_whiteboard_svg accept vault-relative out paths only
(they are reachable by the assistant and the control channel). The CLI places absolute
--out files itself via the new notescraft_engine::render_pdf; the UI export worker renders
and the live session writes.
