Summary

Configure swayidle to lock screen (swaylock) after 15 minutes of inactivity
Turn off display (DPMS) after 60 minutes, auto-restore on activity
swaylock themed with Catppuccin Macchiato to match existing Sway config
Add Mod4+l keybinding for manual screen lock
Add PAM service for swaylock authentication
Disable system suspend/hibernate entirely (workstation should never sleep)

What changes

All changes in nixos/ringtail/configuration.nix:

security.pam.services.swaylock — required for swaylock to authenticate on NixOS
systemd.sleep.extraConfig — blocks all sleep/hibernate modes
programs.swaylock (home-manager) — lock screen appearance config
services.swayidle (home-manager) — idle timeout daemon with lock + DPMS events
New keybinding Mod4+l for manual lock

Deployment and Testing

mise run provision-ringtail
Verify swayidle is running: systemctl --user status swayidle
Test manual lock with Super+l
Verify display DPMS off after idle (can lower timeout temporarily to test)
Confirm machine does not suspend: systemctl status sleep.target

Add screen lock and idle management to ringtail 9beb6dc055

Configure swayidle + swaylock for automatic screen locking after 15
minutes of inactivity and display power-off after 60 minutes. Swaylock
uses Catppuccin Macchiato theme to match the existing Sway config.
Also adds Mod4+l keybinding for manual lock and disables system
suspend/hibernate entirely.
