/**
 * Warn when a free-form key/value map appears to carry a plaintext secret.
 *
 * Glue connection properties and job arguments are open-ended string maps that
 * are emitted verbatim into the CloudFormation template. A literal secret placed
 * there is stored in plaintext in the template, `cdk.out`, and source control.
 *
 * This emits a suppressible synthesis-time warning (never an error - the map is a
 * legitimate escape hatch) when a key looks secret-like AND its value is a plain
 * literal. Values that are tokens - `SecretValue` (`{{resolve:...}}`), `Fn::*`
 * intrinsics, or other unresolved references - are assumed to be handled securely
 * and are not flagged.
 *
 * @param scope the construct used as the annotation scope
 * @param values the key/value map to inspect (may be undefined)
 * @param warningCode the `addWarningV2` acknowledgement code
 * @param remediation guidance appended to the warning message
