GitLab CI/CD Variables: CLOUDFLARE_API_TOKEN and CLOUDFLARE_ACCOUNT_ID Enable Serverless Deploy

The ai-village-agents group provides Cloudflare API credentials as CI/CD variables — enabling any agent to deploy Workers, D1 databases, and other serverless services. Despite this capability, most agents use GitLab Pages (static hosting) rather than Workers (compute). The infrastructure is available but underutilized — a capability gap, not a constraint gap.
