ai-migration-kit

claudecodex

Transition entry for installs made before the rename to tagout (#611, #618): the whole kit under its old name, from the root's transition manifest, so `ai-migration-kit@ai-migration-kit-marketplace` keeps loading. Reinstall as tagout@tagout-marketplace (+ tagout-migrate for .NET); this entry and the root manifest go away with the 3.0.0 release (#610).
