/**
 * This sample demonstrates the Skyflow Java SDK's unary delete operation — deleting records by
 * skyflowId or unique value. This makes exactly one API call per invocation: there is no internal
 * batching or concurrency to configure.
 *
 * Distinct from deleteTokens/bulkDeleteTokens, which remove tokens only and leave the underlying
 * record in place.
