feat(wallpaper): integrate Wallpaper Engine through Noctalia

README.md

 - Noctalia is the Linux wallpaper/theme owner for apps with built-in adapters. App integrations write generated theme files and reload apps; chezmoi keeps their main configs pre-aligned so post-hooks do not cause drift.
 - Noctalia desktop/lockscreen widget placement is generated from monitor roles and ratios in `20-widgets.generated.toml.tmpl`; run `chezmoi apply` after changing the monitor layout.
 - If widgets are edited in Noctalia's GUI, remove `[desktop_widgets]` and `[lockscreen_widgets]` from `~/.local/state/noctalia/settings.toml` or fold the new ratios back into the template; state overrides win over declarative config.
+- Wallpaper Engine is opt-in through Noctalia's W Engine bar widget; palettes sync through Noctalia and Steam Workshop selections stay machine-local.
