Magneto v0.9.2

Smoother download progress, plus small fixes from a code review pass.

• Progress bar animates smoothly
• Magnet adds no longer show false "timed out" during slow resolve
• Removal cleanup no longer purges still-resolving torrent
• Config file is written atomically
• Fixed Windows fallback opener mangling magnet links

Install

• Windows: Magneto_0.9.2_x64-setup.exe. Unsigned, so SmartScreen
  warns on first run ("More info" then "Run anyway"), and Windows asks once
  to allow network access for the daemon.
• Linux: .deb, .rpm, or .AppImage. The AppImage needs fuse3
  (preinstalled on most desktops; otherwise run with
  --appimage-extract-and-run).
• macOS: build from source for now.

This is still an early release. Expect rough edges.
Thank you.
