Subject: [PATCH 17/19] Minimize Docker images and automate relasing docker
 images (#31)

* Initial plan

* Implement multi-stage Docker builds to minimize image size

Co-authored-by: yutaro-sakamoto <80912876+yutaro-sakamoto@users.noreply.github.com>

* Add comprehensive size reduction summary documentation

Co-authored-by: yutaro-sakamoto <80912876+yutaro-sakamoto@users.noreply.github.com>

* Remove OPTIMIZATION.md and SIZE_REDUCTION_SUMMARY.md documentation files

Co-authored-by: yutaro-sakamoto <80912876+yutaro-sakamoto@users.noreply.github.com>

* fix: Dockerfile and utf8.Dockerfile

* build: add build configuration files

* fix: update docker-compose.yml

* ci: run example programs in a Docker container

* chore: rename Makefile to run.sh

* fix: copying built files

* fix: CLASSPATH defined in Dockerfile

* ci: improve workflow triggers

* ci: add experimental code that pushes docker images to DockerHub

* fix: create an image with the tag `latest`

* ci: deploy only when workflow_dispatch

* ci: change settings to disable debug mode

* build: change build-config.json to release new images

* doc: update README.md

* fix: apply copilot suggestions

* chore: update Dockerfile

* ci: add checks of versions of installed software

-In order to "Hello World" program, run the following commands in the docker container
+リリースするバージョンに合わせて、build-config.jsonを編集します。
+* opensource_COBOL_4J_version: Dockerイメージにインストールするopensource COBOL 4Jのバージョン
+* Open_COBOL_ESQL_4J_version: DockerイメージにインストールするOpen COBOL ESQL 4Jのバージョン
+* version_string_prefix: リリースするDockerイメージタグのプレフィックス
+  * 例えば20250929を指定すると、以下の3つのタグを持つDockerイメージがビルドされ、Docker Hubにプッシュされます。

-In order to launch the environment with a database server and a client with opensource COBOL 4J Open COBOL ESQL 4J installed, run the following command.
+* ワークフロー名: `Build and Push Docker Image`
+* ブランチ: `main`
+* 入力パラメータ: `push_to_dockerhub`に`true`を指定
 
-```bash
-cd docker-compose
-docker compose up -d
-docker attach oc4j_client

+これによりDockerイメージがビルドされ、Docker HubにDockerイメージがプッシュされます。
 
-Run the following in the docker container and execute sample programs of Open COBOL ESQL 4J.
