sumof: patch notes 1.0.2

Updated the App Store description and keywords — trying to find ones that actually work. But that alone isn't really enough to call an update, so I added German and French localization too, and updated the screenshots for both languages.

Claude suggested that once impressions hit a certain level, the conversion rate data would start to mean something. But if impressions go up and conversion stays low, that's depressing. And if impressions don't go up at all, that's also depressing. At this point I'm just hoping to get struck by a money lightning.

There was also a little incident. The review team flagged my app for "designated hardware pairing" and asked me to send a demo video. I don't have anything like that in my app. I replied saying so, and it got resolved pretty quickly — but still. Not the end of the world, but it did eat up some time and energy for nothing. Goes without saying it didn't help my trust in the review team, either.
