Implements the shell theme manifest layer from THEME_SYSTEM_PLAN.md §4-5: ShellTheme/WindowSpec/Slots/Tokens/LayerRule types, TOML discovery (user -> system -> compiled-in builtin), one level of `extends` deep-merge, deny_unknown_fields validation naming the offending key, slot module-name validation, and css() token substitution with an extra.css overlay. load() never fails, falling back to the compiled-in builtin and logging once. Ships exactly one builtin manifest, liquid-motion, describing breadbar/breadbox as they exist today (not the design-doc demo, which disagrees with the code on bar side margin, launcher geometry, and the easing curves). Compositor rules and surface specs are keyed by layer-shell namespace and cover all five breadbar namespaces plus breadbox/breadbar-panel/breadbar-dismiss. watch() is gated behind the existing `gtk` feature (gio::FileMonitor is a gtk4 dependency); the rest of the module is gtk-free so bread and breadcrumbs can validate a theme without linking GTK. No consumer changes — breadbar/breadbox still use their own hardcoded values.
