Adds an experimental `llms` config option that emits, at the end of the
build, a raw markdown version of each page (includes expanded, rewrites
applied), an llms.txt index following the sidebar order, and an
llms-full.txt bundle. Root locale only; dynamic routes are skipped.
See https://llmstxt.org/ and vuejs/vitepress#4590
BREAKING CHANGE: `useLocalNav` and `useSidebar` are removed in favor of `useLayout`. To migrate, just do find and replace. Sidebar controls are no longer exported, but I didn't find any usage on GitHub. If there is demand, we can export respective composables later. `DefaultTheme.DocSidebar` and `DefaultTheme.DocLocalNav` types are also removed.
