feat(skills): add Docker image update check to wren-mcp-setup

[goldmedal]

Summary

• Adds a "Check for a newer image" sub-section to Step 2 of the wren-mcp-setup skill
• Before docker run, the skill now guides users to compare the local wren-engine-ibis image digest against the remote registry and pull only when a newer version is available
• Includes a note to stop and remove the existing container if a new image was pulled
• Bumps wren-mcp-setup to v1.2 in SKILL.md, versions.json, and index.json

Test plan

• Follow the skill — verify the image check section is clear and the bash snippet runs correctly on a machine with an existing image
• Verify the skill version check at startup reports 1.2 as installed
