Install the backend SDK

Requires Go 1.26.1+. The module path is github.com/peacewalker122/mapper (consumed directly from the mapper-be repository via the Go module proxy — no separate registry upload needed):

go get github.com/peacewalker122/mapper@v0.1.0

Replace v0.1.0 with the latest mapper-be release tag. Then import the packages you need:

import (
  "github.com/peacewalker122/mapper/mapper"
  "github.com/peacewalker122/mapper/mapperhttp"
)

Verify the setup with:

go vet ./...
go test ./...

Next: wire the service and HTTP adapter as shown in the Backend SDK guide.
