feat: adopt central-ops shared packages and reusable workflows

- Replace inline beta/release workflows with central-ops reusable callers
- Adopt pkg/version.Detect() in main.go (removes inline debug.ReadBuildInfo)
- Adopt pkg/httputil.CORSMiddleware in internal/mcp/server.go Handler()
- Add require + replace directive for github.com/RandomCodeSpace/central-ops
