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.

+## 2026-07-12 — #76 closed: hibernate V3 PASSED on TuringMachine (this commit)
+- **Task:** BACKLOG #76 `[human]` closure — Bernardo reports the V3 check.
+- **Did:** Bernardo ran the real power-cycle on the T14s (LUKS + btrfs
+  `@swap` swapfile): hibernate → power off → single LUKS unlock →
+  session restored, "flawlessly". Deleted #76; HARDWARE-QUEUE resume
+  entry pruned (outcome recorded here + ROADMAP ✓-entry updated);
+  Decisions note marked shipped. The **no-swap Hibernate notify** check
+  stays open in HARDWARE-QUEUE as the one leftover.
+- **Verified:** V3 (human, real hardware). Docs-only commit otherwise.
+- **Pending:** no-swap notify check (needs a swapless session or
+  temporary `swapoff -a`).
+- **Next suggestion:** #89 slice 2 — the override-icon layer.
