Method show_change_diff_from_file_ops

atomic-cli/src/commands/diff/helpers.rs:336–346

Show diff using the semantic layer (FileOps). This is the preferred path - it displays line-level and token-level changes directly from the stored CRDT operations, without recomputing. Building the `Vec ` is delegated to the reusable [`change_file_diffs`] builder; this method applies the positional file filter and prints, preserving `atomic diff -c ` output exactly.
