[BUG] Edit/Write tools convert CRLF to LF on Windows, breaking Delphi projects

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

I am in Windows with Delphi projects
My files originally had CRLF line endings
When Claude Code edits files using Edit/Write tools, they're saved with LF endings
RAD Studio/Delphi requires CRLF and shows warnings
This seems to be a recent change as it hadn't been happeing up to today.
Windows 11. Sonnet 4.5, Claude Cod Max. OpeusPlan. Files affected are Delphi 'text' type files. i.e. .pas, .dfm, /dpr, etc.

What Should Happen?

Tools should preserve original line endings or respect Windows default (CRLF)
