v0.8.0

Minor Changes

• d53f4f4: Scenes: light/dark stage theming over the wire. kino:init gains an optional
  theme and a new kino:setTheme command follows the embedding site's live theme
  toggle without reloading the iframe. ScenesPlayer takes sceneTheme (distinct
  from theme, which styles kino's chrome), createScenesProvider takes theme and
  returns ScenesProvider with setSceneTheme, and the host applies the theme to
  documentElement as exactly one of dark/light plus the matching colorScheme.
  The pip mirror inits with the current theme and follows flips alongside the
  master. Dark stays canonical: omit everything and existing hosts behave
  exactly as before.
