Add opt-in nomarchy.updates (modules/home/updates.nix): a nomarchy-updates
checker on a systemd user timer (interval, default daily) that surfaces a
Waybar indicator + a notification when updates are available, without ever
changing anything (you still run sys-update / flatpak update).
It counts:
- flake inputs behind upstream — only the flake's DIRECT inputs (root.inputs:
nixpkgs, the Nomarchy input, home-manager, stylix…), not the transitive
closure, via `git ls-remote` vs the locked rev. Offline → skipped, never a
false alarm.
- Flatpak updates, when the flatpak CLI is present (.flatpak, gated on
services.flatpak being on) — Bernardo's suggestion.
Waybar custom/updates self-gates (hidden until the timer finds something;
accent " N", signal 9 for instant refresh), in the generated bar and both
summer whole-swaps. The notification fires only when the count grows, so a
daily timer doesn't nag. Click → the upgrade flow in a terminal (sys-update /
flatpak update, each confirmed). nomarchy-updates ships always on PATH and
self-gates so the static whole-swap bars can exec it even when the feature
is off.
Verified: flake check clean; home generation builds; the jq direct-input
filter + status self-gate exercised against the real flake.lock; script
passes bash -n. Pending an on-machine check (ls-remote/notify/timer need a
live session).
