Ralph Upgrade

Upgrade the Ralph multi-agent runtime in the current repository using the tagged scaffold surface in https://github.com/tolulawson/ralph-harness.

This is the main external entry point for refreshing an existing install without overwriting project-owned runtime data.

UPGRADING.md is the canonical upgrade source of truth. This skill is only the execution adapter for that guide.

Use When

• The current repository already has the Ralph harness installed.
• You want to move that install to a newer tagged Ralph scaffold release.
• You want the active coding agent to preserve project-owned runtime files while refreshing only scaffold-owned files.
