Bug Description
If you have BOM markers at the top of code files (due to sharing code with Windows users)
when Claude shows a diff in the GUI it shows the first line of the file as changed, every time.
The left "Original" side shows a file with type UTF-8 BOM and no changes
The right "Proposed" side shows a file with type UTF-8 and a change adding ZWNBSP to the first character.
Applying the change doesn't change the BOM marker - but this makes the GUI diff hard to use as it always scrolls to the top of the code even if the changes are much further down.
