refactor(build): own all task spinners in build()

bundle() and generateSitemap() are plain workers now; build() wraps
them in tasks alongside render. Keeps the MPA asset copies and the
MPA client build under the bundles spinner instead of running after
it resolves, and skips the sitemap spinner when sitemap generation
is off.
