feat:buffer-diff: Add syntax-aware buffer diffing with difftastic
Introduce enhanced buffer comparison with saved file using difftastic for syntax-aware diffing, with a fallback to regular unified diff if difftastic is unavailable. Output is displayed in separate buffers, leveraging ansi-color for improved readability. Also includes comprehensive integration tests covering the diff workflow, handling cases like added, removed, and modified lines, and ensuring graceful handling of special cases and errors.
