fix(minimax): restore migrate-command, remove broken migration file, fix validator typo

- Restore src/commands/migrate-command.ts to dev branch state (was truncated)
- Remove src/config/rename-minimax-profile.ts (circular export causing build break)
- Fix mm.settings.json path typo in api-key-validator.ts

Build now passes: bun run typecheck && bun run lint:fix
