feat: add local Docker build script and update compose configuration

- Introduced a new script `docker-build-local.sh` to build a local Docker image and start services using Docker Compose.
- Updated `docker-compose.yml` to allow dynamic pull policy configuration via the `CLI_PROXY_PULL_POLICY` environment variable.
- Modified `Dockerfile` to support build arguments for Go module proxy settings during the `go mod download` step.
