Fix use-after-free bug in JSON parsing error messages

When workspace package.json parsing fails, error messages contained references
to freed memory for both line text and file paths, causing corrupted output.

This patch fixes two separate use-after-free issues:

1. Line text corruption: Enable clone_line_text=true for CLI logger so line text
   gets cloned before source buffers are freed
2. Path corruption: Extend cloneLineText() to also clone file paths when
   line text cloning is enabled

The fix ensures error messages display correctly instead of showing corrupted
characters like "�������������������" and garbled paths.

Fixes workspace JSON parsing error display corruption.
