/**
 * AWS CDK + CDKTF framework detector (spec-07).
 *
 * Like Pulumi, CDK and CDKTF programs are ordinary TS/JS/Python/Go that
 * construct resources — already parsed for the call graph. We recognize the
 * construct instantiations and emit extra `CDK` / `CDKTF` resource nodes +
 * reference edges, leaving the normal call graph untouched.
 *
 * The distinguishing shape: a construct's **first** argument is the scope
 * (`this`/`self`/an identifier) and the **second** argument is the logical id
 * string — `new s3.Bucket(this, "MyBucket", { … })`. (Pulumi puts the name
 * first.) We never synthesize CFN/Terraform; this is static detection only.
 *
 * Scope conservatively: a construction is only recognized when its root
 * identifier is bound to a CDK (`aws-cdk-lib`, `@aws-cdk/*`, `aws_cdk`) or
 * CDKTF (`cdktf`, `@cdktf/*`) import. Unknown roots → no nodes.
