Walkthrough

Removed the StaleAssetRecovery component and its root-document integrations. Removed server support for the X-Build-Id header and /build-version endpoint, and stopped applying default Cache-Control: no-cache headers to HTML responses. Updated server-app release-note guidance with placeholder wording, allowed area and type values, and package-change rules.
