docs(agent): close #76 — hibernate→resume V3 PASSED on TuringMachine

Bernardo ran the real power-cycle on the T14s (LUKS + btrfs @swap
swapfile): hibernate → power off → single LUKS unlock → session
restored. BACKLOG #76 deleted; HARDWARE-QUEUE resume entry pruned
(outcome recorded in the remaining no-swap-notify entry, JOURNAL, and
the ROADMAP ✓-entry); Decisions hibernation note marked shipped. The
no-swap Hibernate notify check remains the one open leftover.
