PDF-to-image rendering now cleans up error messages, including Windows network path prefixes, and handles a new move-failure case

What

When Claude Code converts a PDF page to an image (using the pdftoppm tool, part of reading PDF files), it now cleans up the error text before showing it to you:

  • Temp-file paths embedded in the underlying tool's error output are replaced with the original filename, so errors reference the file you actually gave it
  • Windows extended-length and UNC path prefixes (\\?\UNC\, \\?\) are stripped out of error text
  • A distinct error is now reported if moving the rendered page images into the output folder fails
Why

This makes PDF rendering failures easier to understand, especially on Windows, where raw error text could otherwise show confusing internal path syntax instead of your file's name.
