Variable declared without type or validation

What it checks

Variable: no `type` declaration and no validation block.

Where it applies

Terraform: variable

CloudFormation: no CloudFormation type maps to these resources yet.

How to fix it

1. Add type = string / number / list(string) / object({...}). For range-bound numerics, add validation { condition = ..., error_message = ... }.
