/**
 * Datasets seeder for `respan demo`.
 *
 * Creates the demo datasets (see dataset-fixtures.ts) and bulk-loads their rows,
 * then tears them down for `respan demo clear`. Deduplicates by dataset name so
 * re-runs never create duplicates. All dataset-specific logic lives here; the
 * orchestrator stays service-agnostic.
 *
 * Rows are written via `bulkCreateDatasetLogs` (POST .../logs/bulk/), which is
 * synchronous and returns success/error counts. Each row's `input` object becomes
 * the row's mapped variables; `expected_output` is JSON-stringified so the grader
 * sees valid JSON (a raw object is coerced to single-quoted python-repr).
