Fix Windows badge API for windows-rs 0.61 + add libfuse2 for Linux AppImage

- Move BOOL import to windows::core (removed from Win32::Foundation in 0.61)
- Move CreateBitmap import from WindowsAndMessaging to Win32::Graphics::Gdi
- Wrap nullable handles in Some() for GetDC, CreateCompatibleDC,
  CreateDIBSection, ReleaseDC (new Option<T> API in 0.61)
- Add .into() for all SelectObject/DeleteObject GDI handle args (now HGDIOBJ)
- Use FONT_PITCH_AND_FAMILY type directly in CreateFontW instead of u32 cast
- Make DrawTextW slice mutable (&mut [u16] required in 0.61)
- Use hicon.unwrap_or_default() for SetOverlayIcon (takes HICON not Option<HICON>)
- Add libfuse2 to apt-get for Linux AppImage bundler (FUSE mount fallback)
