Expand description

struct rusage du kernel : statistiques de ressources (getrusage(2)).

Layout #[repr(C)] fidèle au kernel (2 timeval + 14 long), cibles 64-bit (ADR-014). Plusieurs champs ne sont pas maintenus par Linux (legacy BSD) et restent à 0 — on les expose tels quels (transparence, kernel = bible).
