Bernardo Magri 8853f6ae49 feat(idle): no double-unlock after an encrypted hibernate resume
hypridle locks hyprlock before every sleep -- right for suspend, but
redundant for hibernate: the LUKS passphrase entered at boot already gates
the resume, so the user typed a password twice. Add a nomarchy-hibernate-
unlock systemd unit (WantedBy hibernate.target, After systemd-hibernate.service
=> runs post-resume) that dismisses hyprlock, gated on the disk being LUKS-
encrypted. Suspend (and the RAM-resume phase of suspend-then-hibernate) keep
locking -- they have no passphrase gate; an unencrypted hibernate keeps its
lock too. idle.nix gains a pointer comment; roadmap item marked done.

# hyprlock + hypridle — screen locking and idle management, themed from
# theme-state.json. One concern, one file: hypridle drives WHEN (idle
# lock, display off, suspend, lock-before-sleep), hyprlock is the
# themed lock screen itself (also behind the power menu's Lock entry).
