- Preserve symlinks when writing files atomically in write_atomic() - Update test to verify correct symlink preservation behavior - Apply rustfmt formatting This fixes the issue where cargo add would replace symlinked Cargo.toml files with regular files, breaking the symlink to the original target. Fixes #15241
