• Added --no-overwrite / -n option to prevent overwriting output files.
  If the destination file already exists, OCRmyPDF exits with code 5
  (OutputFileAccessError). {issue}1642
• Fixed text layer stretching in the fpdf2 renderer for widely-spaced words.
  The horizontal scaling (Tz) was incorrectly stretched to fill inter-word gaps
  instead of relying on Td positioning, causing text selection to highlight far
  beyond the actual word boundaries. {issue}1635
• Fixed optimize=2 or optimize=3 crash when using the Python API without
  explicitly setting jpg_quality or png_quality. {issue}1641
• Fixed verapdf availability check crashing with NotADirectoryError on
  some platforms. {issue}1638
