Add a session-lock screen and idle management to the Hyprland-native
subdirectory, enabled through the desktop aggregator.
hyprlock draws through the compositor session-lock protocol, themed by
Stylix, with a centered field and clock. Super+X locks directly through a
guarded launch so the key works without the idle daemon.
hypridle locks on idle and powers the displays off, with tunable timeouts,
and locks before every suspend. Lid-close routes through logind to suspend,
which the pre-sleep lock covers, so the lid lands at a locked screen.
Add the hyprland-desktop spec, ADR 0003 recording the compositor choice
over Sway/KDE/niri, and the task breakdown (0021-0030) that decomposes
the desktop into granular grouped modules. Record the corrected host GPU
facts (zeus is AMD, raichu the sole Nvidia machine) in CLAUDE.md.
