With v2 becoming the stable release, v1.x moves from the site root to /v1/ and stops deploying the site itself: the combined site is built and deployed from main, which builds this branch's docs into /v1/ via the new scripts/docs/build.sh. A `docs` CI job runs that same script, so a change that breaks the v1 docs fails on this branch rather than at main's next deploy. site_url and the package's Documentation URL move to /v1/ so canonical links, the sitemap, and llms.txt point at where these pages are actually served. The README and landing page now describe v1.x as the maintenance line and send new users to the v2 docs, and every install line pins `mcp<2` so a reader following these docs stays on the 1.x line now that an unpinned install selects 2.x.
