Add native Kotlin Android client to the Android section

[Dking08]

Updated the Android section to list both available F-Droid apps with short descriptions.

I built croc-app, a native Kotlin/Jetpack Compose Android client with a modern, mobile-first UI, and wanted to add it alongside the existing listing so users know it's available.

Cool app! I was able to send files from my mobile device through my relay without telling your app my relay password. And I received them on desktop with GUI https://github.com/abakum/crocgui/releases/tag/v1.11.56. My application is localized for Russian, Turkish, Japanese, and Chinese-speaking users. It has a WebDAV access mode for the sender's files, which allows you to, for example, watch a single concert number without downloading the entire concert video. It also includes a chat with video conferencing through the croc tunnel, call recording (and for desktop, screen sharing of browser tabs, any app window, or the entire screen). You can also download the mobile version. https://www.rustore.ru/catalog/app/com.github.howeyc.crocgui
Try a relay that allows this https://github.com/abakCroc/croc. Look PR at #1106.

Awesome app. Found it last week when introducing a friend to croc. The best document transfer app alongside LocalSend.

@abakum
I am glad you liked the app.

My app, croc-app work entirely on croc so all relay handling and other operations are done by croc.

Currently croc-app is a modern interface for croc with some utility. Additional features can be added depending on its userbase.

I will surely try your app; building on existing croc features sound intresting.

@schollz - just following up on this when you get a chance.

Since opening the PR, a few people in the discussion have shared positive feedback about the app, and the project has also grown a bit (currently 35 GitHub stars). Since this change is only adding an additional Android client listing and doesn't affect functionality, I wanted to check if there's anything you'd like changed before it can be merged.

Thanks
