The "next" dist-tag was a workaround for Docker builds that can't resolve
workspace:* — but "next" has gone stale (1.55.2-next.1) while "latest" is
at 1.56.5. Renovate doesn't cover showcase/, so these never auto-bumped.
Switch all 19 showcase package.json files to "latest".
Add interrupt demos (Strategy B), byoc-json-render demo (zero-tool
agent + @json-render frontend), and shared-state-streaming (per-token
STATE_SNAPSHOT emission via tool-call argument interception).
Spring AI moves from 4 unsupported features to 0.
The showcase framework directories better reflect their role as
integration examples rather than distributable packages.
Renames showcase/packages/ -> showcase/integrations/ and updates
the test docker-compose file reference accordingly.
