Module text_diff 

The workspace’s single line-diff owner.

Every unified-diff renderer in the codebase — orchestration run-record diffs, the ast.dry_run preview, and the harn package publish index preview — routes through render_line_diff so the algorithm choice and context radius live in exactly one place. Callers supply their own file header (--- a/… / +++ b/…, /dev/null, etc.); this module owns the @@ hunk body and the +/- line counts.
