Demo: Faster Workspace Setup

This demo release shows how to announce infrastructure and developer-experience improvements in the changelog.

One-command workspace setup - New projects can start their app and backend services from the same command.
Clearer environment checks - Missing configuration is surfaced earlier with focused messages.
Reusable setup scripts - Local agents and developers can share the same project bootstrap path.

Cleaner onboarding path - Setup steps are grouped around the order developers actually follow.
Reduced template noise - Optional integrations stay out of the way until they are configured.
