/migrate
Guided migration and upgrade — dependency major version bumps, API breaking change adaptation, language edition upgrades, and build system migrations. Preserves compatibility through incremental steps with rollback points. Auto-saves migration report to .artifacts/ TRIGGER when: user asks to upgrade a dependency, bump a major version, migrate an API, switch build systems, or adapt to breaking changes from a library/framework update. DO NOT TRIGGER when: user is adding a new dependency (use /design), or making internal design changes unrelated to external API/version changes (use /refactor or /refactor breaking for destructive internal redesign).
