/**
 * CDK output for the serverless (Lambda + OTel extension) estate.
 *
 * Emits a single self-contained TypeScript construct file the customer
 * drops into their own CDK repository — reviewable, forkable, owned by
 * them. Nothing here executes CDK; this module is a code EMITTER, the
 * same shape as `forwarderWriteTerraform()` on the Terraform side. The
 * Terraform path stays; this adds the CDK one.
 *
 * Three concerns, one construct file:
 *   1. The engine in the execution environment — a LayerVersion reference
 *      plus a per-function attach helper (layer + env vars).
 *   2. The Coralogix TCO policy — a Lambda-backed custom resource doing
 *      READ-MODIFY-WRITE against the real (recovered-from-the-wire) API:
 *      `PUT https://api.<region>.coralogix.com/mgmt/openapi/5/dataplans/log-policies/v1`
 *      on the REGIONAL host, which is an ATOMIC WHOLE-LIST OVERWRITE. A
 *      blind PUT clobbers policies the customer created by hand, so the
 *      resource merges by policy name. See `coralogixTcoApiContract()`.
 *   3. The CloudWatch remainder — SubscriptionFilter per named log group
 *      targeting the receive-role Lambda, plus an EventBridge rule on
 *      `CreateLogGroup` driving a small subscriber function so NEW log
 *      groups are covered by rule, not by remembering.
