feat: Add CI/CD workflows and Cloudflare DNS Terraform

## GitHub Actions Workflows

### deploy-railway.yml
- Automated Railway deployments on push to main
- Change detection for AIops, Analytics, Codex, and Infra
- Manual dispatch with service selection
- Deployment summary in GitHub Actions

### sync-satellites.yml
- Automatic sync from monorepo to satellite repos
- Pushes services to BlackRoad-OS organization repos:
  - AIops → blackroad-os-infra
  - Analytics → blackroad-os-core
  - Codex → blackroad-os-operator

## Cloudflare DNS Terraform (infra/cloudflare/dns-records.tf)

### blackroad.systems Subdomains
- api, core, operator, beacon, prism, docs
- console, infra, archive, demo, research
- finance, legal, devops, lab (packs)

### blackroad.io Subdomains
- app, home, api, creator, os

All records configured as proxied CNAMEs to Railway services.
