name: Update Versions and Release Helm Chart

# 毎週月曜 3:00 AM JST（日曜 18:00 UTC）に実行。
#  - 主アプリ = Claude Code CLI（npm: @anthropic-ai/claude-code）の最新版を確認
#  - base image = gateway(nginx) / manager(python) の最新 Alpine タグを確認
#  - 主アプリが更新: values.yaml / Chart.yaml / README 履歴を更新しコミット → タグ + Gitea リリース + チャート publish
#  - base image のみ更新: values.yaml を更新してコミットのみ（リリースなし）
#
# セッションイメージのビルドは session-image.yaml が担当する（このワークフローが
# Chart.yaml を push した結果として発火する）。
