orkunisitmak/nashi-app ? reverse-engineered prompt

Build me Nashi, a simple file toolkit app that makes it easy to drag in files and quickly convert, edit, and export them.

I want it to feel friendly and fast, with a wheel style action picker, quick keyboard shortcuts, and a clean home screen that shows the most useful tools first. It should handle common file tasks like image, PDF, audio, and video conversions, plus crop and annotation style editing, video trimming with in and out points, QR code reading, and downloading media from public web links. Keep the actual file work local when possible, and show clear progress while things run.

Please make it work well on macOS, and if the project supports Windows too, keep the Windows version native and usable. Include a simple setup flow for any missing helper tools, and make updates feel safe and automatic. Use the current docs online if you need to confirm any details.
