- Mobile: the Return key now inserts a newline instead of sending (send via the button, like
every native chat app). Desktop keeps Enter=send / Shift+Enter=newline.
- Image preview: hide the on-screen +/- zoom buttons on mobile (pinch-to-zoom covers it).
- Desktop (Electron): a will-download handler saves straight to the OS Downloads folder with no
"where to save?" dialog, de-duping the name if it exists. NOTE: desktop code only — NOT
published to the update feed (needs an explicit desktop rebuild/publish).
