feat: add self-built Docker image from local hapi source

Add a new Docker image variant (tag: self) that uses compiled binaries
from the hapi self branch instead of installing from npm.

- self/Dockerfile: runtime image copying pre-built binary by arch
- self/build.sh: local build script from ../hapi/dist-exe
- .github/workflows/docker-build-self.yml: CI workflow to build and
  push multi-arch image to GHCR with tag "self"

via [HAPI](https://hapi.run)
