feat: auto-update Dockerfile with current claude-code npm versionBrowse files
- Add GitHub workflow to automatically check for new claude-code versions daily
- Pin CLAUDE_CODE_VERSION to 2.0.55 (instead of 'latest') in Dockerfile and devcontainer.json
- Workflow creates PRs when new versions are available, ensuring Docker cache invalidation

53+ This PR automatically updates the claude-code version in the devcontainer configuration.
54+
55+ **Changes:**
56+ - Updated `CLAUDE_CODE_VERSION` from `${{ steps.current-version.outputs.version }}` to `${{ steps.npm-version.outputs.version }}`
57+
58+ This ensures Docker cache is invalidated when rebuilding images, allowing users to get the latest claude-code version.
