            This PR automatically updates the claude-code version in the devcontainer configuration.

            **Changes:**
            - Updated `CLAUDE_CODE_VERSION` from `${{ steps.current-version.outputs.version }}` to `${{ steps.npm-version.outputs.version }}`

            This ensures Docker cache is invalidated when rebuilding images, allowing users to get the latest claude-code version.
