docs(agent): correct #76 V3 scope — dev box isn't a Nomarchy install

The dev box runs Bernardo's own NixOS (TuringMachine, 25.11), not
Nomarchy — so hibernating it tests that config's hibernate, not
Nomarchy's oom.nix/patch-template/rofi wiring, and can't close #76's V3.
Its layout (LUKS cryptroot + btrfs @ + /swap/swapfile + resume_offset)
does resume, which corroborates the MIGRATION.md runbook, but nothing
more. Rescope the two #76 HARDWARE-QUEUE entries to require a machine
actually running Nomarchy (a Latitude install, or the dev box after
migration), and fix the matching reference in the BACKLOG #76 stub.

Verification: V0 (docs/agent-notes only).
