SitemapGenerator Cache Adapter

The sitemap_generator gem writes files to disk, which doesn't work on Kubernetes or Heroku. This adapter stores sitemaps in Rails.cache instead, making them work seamlessly with ephemeral storage and multi-pod deployments. Published as a gem for Rails teams running on modern infrastructure.
