描述

Currently uutils' diffutils only implements the diff executable.

But GNU's diffutils also provide cmp, diff3 and sdiff.

This issue is a tracker for the implementation of the sdiff utility.

Documentation: https://www.gnu.org/software/diffutils/manual/html_node/Invoking-sdiff.html.

研究方向
Review the existing diff implementation in src/diff.rs to understand project structure. Study the GNU sdiff documentation linked in the issue. Plan a new module src/sdiff.rs implementing side by side diff output, handling options like w and l. Write tests and integrate into the command line interface.
