feat(core): migrate system state to unified declarative JSON

- Consolidate all configuration toggles (suspend, idle, waybar, etc.) into ~/.config/home-manager/state.json
- Introduce nomarchy.toggles and nomarchy.hyprland options in Nix
- Inject toggle states into all bin/ scripts via environment variables
- Update toggle scripts to mutate JSON and trigger background rebuilds
- Add a migration script to transition legacy flag files to the new format
