TanStack Project Migrate

Move an existing application from a foreign or materially older stack to the house baseline without breaking it between slices. This is not gap remediation.

Apply runtime-trust.md, shared-version-policy.md, version-policy.md, the four local baseline references, and migration-checklist.md. Copied policy does not enlarge the explicit migration scope. Do not produce a migration-plan artifact; migrate the application directly in verified slices. Resolve every relative link in this file against the directory containing this SKILL.md, never the plugin skills root.
