fix: use proj.device instead of hardcoded cuda, fix README typos

Browse Source 
- Replace hardcoded device="cuda" with proj.device in SIGReg for
  portability (e.g. macOS MPS, CPU)
- Fix "Both functions accept" → "This function accepts" (only one
  function is shown)
- Fix "please reference in your paper" → "please reference it in
  your paper"
