Move product documentation into the Builder repository

[kof]

Problem

Product documentation currently lives in webstudio-is/webstudio-community, separate from the CLI and Builder code that defines documented behavior. Cross-repository MCP documentation synchronization has proven unreliable and requires additional credentials and release coordination.

Desired outcome

Make webstudio-is/webstudio the source repository for all product documentation and retire webstudio-is/webstudio-community after the migrated documentation is published and verified.

Product scope

• Preserve the current documentation content, navigation, assets, and useful Git history under /docs in the Builder repository.
• Keep the public docs.webstudio.is URLs stable.
• Generate and validate MCP documentation entirely within the Builder repository.
• Publish GitBook from a docs branch that merges the exact revision of each successful release and records its CLI version, so public documentation never leads the installable CLI.
• Update repository links and automation that refer to the Community repository.
• Repoint GitBook to the Builder repository.
• Delete the Community repository only after the Builder-hosted documentation is verified in production.

Constraints

• GitHub Discussions will not be migrated.
• Documentation publishing must not depend on a cross-repository token or dispatch.
• The docs branch is a publication branch and is not edited directly.
• Existing Builder release and publish paths must remain intact.
• Preserve a recoverable repository mirror before deletion.

Acceptance criteria

• Documentation sources and assets are present under Builder /docs with working navigation and internal links.
• MCP documentation generation and stale-output checks run locally in Builder CI.
• A successful release merges its immutable tag commit into docs and records the released CLI version only after release creation and package publication succeed.
• GitBook publishes /docs from Builder's docs branch without changing public documentation URLs.
• References to Community Discussions or the Community documentation repository are removed or replaced where appropriate.
• Superseded cross-repository automation is removed.
• The Community repository is deleted only after production verification.

Product decision: MCP documentation will be generated from the local CLI source and committed with the same Builder change, rather than generated after an npm release. This removes the automation-PR permission dependency. The public page notes that merged documentation can precede the corresponding published CLI release.

Initial publication branch updated: docs now contains merged PR #5990 plus Webstudio MCP v0.285.0 at commit 2013f20b71. GitBook repointing and production verification remain before Community deletion.
