feat: make quickshell the default bar + notification daemon

The quickshell pilot proved out in daily use; promote it from manual
pilot to the session default. Additive — no hard deletes: Waybar and
swaync stay installed as reserves.

- niri spawns `quickshell` instead of `moonarch-waybar`; Alt+W toggles
  quickshell ⇄ Waybar for the rare fallback
- swaync's spawn-at-startup is commented out so it releases
  org.freedesktop.Notifications for quickshell's own server (verified:
  quickshell owns the name; flip the comment to return to swaync)
- quickshell added to packages/official.txt (config ships automatically
  via moonarch-git's defaults/xdg install loop)

Remaining: push → CI rebuilds moonarch-git → pacman -Syu; niri changes
take effect on relogin.

Both Waybar and swaync stay fully installed as **reserves** (no hard deletes) but are no longer autostarted: Waybar toggles via **Alt+W** (`pkill quickshell` ⇄ `moonarch-waybar`); swaync's `spawn-at-startup` is commented out so it releases `org.freedesktop.Notifications` for quickshell's own `NotificationServer`. To switch back: re-enable swaync's spawn and drop quickshell's `NotifToastHost` from `shell.qml`.

 - **Why**: quickshell has no native config merge/drop-in/plugin system — it picks a single config root by XDG precedence. We want a system-provided bar (`/etc/xdg/quickshell/`) that a user can *configure* (toggle widgets) and *extend* (own widgets) without forking the whole config and losing system updates for their part.
 - **Tradeoffs**: Two behaviours were spiked against quickshell 0.3.0 first, not guessed: (1) a `~/.config/quickshell/` dir *without* a `shell.qml` does **not** displace the system config — so the user's files may live at the natural path. (2) User QML in a foreign dir cannot see our singletons implicitly, but a `qmldir` in the system dir + `import "file:///etc/xdg/quickshell"` exposes singletons **and** components natively (verified: `Theme.accent` resolves; property-injection via `Loader.setSource` is the fallback). Scope kept to **toggle + add** — no per-widget override (expensive: per-slot loader + the hardcoded `Popouts.qml` registry) and no reordering/user-popouts (follow-up). Toggles use JSON (Waybar-familiar, reuses the `NightlightService` FileView+JSON pattern); own widgets stay QML (unavoidable). A user widget rooted at/containing `ModuleBox` must not anchor its direct child with `centerIn: parent` — that hits a pre-existing `childrenRect` binding loop in `ModuleBox` (documented, not fixed here).
 - **How**: New `UserConfig.qml` singleton reads `~/.config/quickshell/moonarch.json` (`{"widgets":{"<key>":false}}`, absent/broken = all on) and probes for `UserWidgets.qml`. New `qmldir` (generated from the `.qml` files) declares all singletons + components for cross-dir import. `Bar.qml` gates each of the 16 widgets on `UserConfig.enabled("<key>")` (self-hiding widgets combine it into their internal `visible`; group `ModuleBox`es hide when all their keys are off) and adds a `Loader` slot (right cluster) bound to `UserWidgets.qml` when present. Still a pilot — the `qmldir` must be shipped when the pilot is later packaged.

+## 2026-07-05 – Quickshell bar: promoted from pilot to default (Waybar + swaync kept as reserves)
+- **Who**: Dominik, ClaudeCode
+- **Why**: The pilot proved out in daily use. Make quickshell the session's default bar **and** notification daemon. "Remove nothing" means no hard deletes — Waybar and swaync stay installed, just no longer autostarted.
+- **Tradeoffs**: Considered a `moonarch-bar` switch wrapper (config-driven bar selection) but rejected as over-engineering — Waybar is only a reserve, so a persistent setting isn't worth it; niri spawns `quickshell` directly and **Alt+W** toggles quickshell ⇄ Waybar. Notifications move to quickshell's own `NotificationServer`; swaync's `spawn-at-startup` is commented out (not deleted) so it releases `org.freedesktop.Notifications` — flip the comment back (and drop quickshell's `NotifToastHost`) to return to swaync. The quickshell config needs no PKGBUILD change (moonarch-git's generic `find` loop over `defaults/xdg/` already installs `/etc/xdg/quickshell/`, `qmldir` included); only the `quickshell` runtime package was added.
+- **How**: `defaults/xdg/niri/config.kdl` — `spawn-at-startup "quickshell"` (was `moonarch-waybar`), swaync spawn commented out, Alt+W bar toggle. `quickshell` added to `packages/official.txt` and moonarch-git `PKGBUILD` `depends` (Waybar + swaync stay in both — reserves, not removed). quickshell's notification stack stays active (`NotifToastHost` in `shell.qml`, `NotificationIndicator` in `Bar.qml`, `notifications` popout). Verified: config loads via `qs -p` with zero binding loops; `niri validate` passes. Remaining manual step: end-to-end deploy (push → CI rebuilds moonarch-git → `pacman -Syu`) and the swaync→quickshell notification handover (test with swaync not running, since a running swaync holds the D-Bus name).
