Add claude-code base image

[tasuku43]

Summary

• Add claude-code/ base Docker image with Claude Code CLI and common dependencies pre-installed
• General-purpose base image: FROM chatwork/claude-code for K8s CronJobs, CI, interactive work, etc.
• No ENTRYPOINT/CMD — jobs provide their own command via K8s command/args or docker run
• Runs as non-root user (claude)
• Claude Code CLI version pinned and auto-tracked via variant mod (GCS latest endpoint)

Included tools

Category	Tools
Core	Claude Code CLI, curl, ca-certificates, git, bash, less
Data processing	jq, yq, unzip
Cloud / CI	awscli, gh (GitHub CLI), python3
Security	gpg, openssh-client

Test plan

• docker build succeeds locally
• docker run ... claude --version returns expected version
• docker run ... whoami returns claude (non-root)
• make test (dgoss) passes — 9/9, 0 failed
