Summary by CodeRabbit

• Bug Fixes
  • Caret (^) characters in text files now display as written instead of being interpreted as formatting escapes, so the viewer preserves the original text. This improves readability for files that contain carets and prevents their surrounding content from being unintentionally formatted.

📝 Walkthrough

Walkthrough

The text viewer now doubles literal carets in file contents before passing them to the renderer. It checks the file position and reports errors if position lookup or expanded-buffer allocation fails.

Changes

Text viewer content handling

Layer / File(s)	Summary
Count and escape literal carets src/menu/views/text_viewer.c	The viewer defines TEXT_VIEWER_ESCAPE_CHAR, counts carets, and doubles each caret in an expanded buffer. It updates the stored length and reports errors if file-position lookup or buffer allocation fails.
