[eric] windows 1.1.57: four fixes — (a) textarea Enter-to-send now actually clears the input (missed editor.innerHTML='' at ChatInput.tsx:181 in the post-send path); (b) textarea draft restore (useDraftLoad) routes through .value instead of innerHTML on Windows so a saved draft repopulates the input on remount; (c) restore the <input type="file"> + attach button on Windows since the original 1.1.54 crash root cause was the contentEditable TSF init not the file input — replacing contentEditable with textarea was the actual fix, file input was over-ablated; (d) relax CSP frame-src to allow http:/https: so BrowserCard iframe can render external sites; (e) gate AgenticCursor's portaled Framer Motion infinite-loop animation on Windows so onboarding panel commit no longer 0xC0000005 segfaults; Mac path untouched
