Pre-generated Stream WatDiv workloads for incremental SPARQL benchmarking (scales 1 and 10)

Two pre-generated Stream WatDiv workloads for evaluating incremental SPARQL query processing. Each ZIP contains static RDF data (static.nt), ordered stream events (stream-events.jsonl), generated SELECT queries (queries.sparql), generator settings and provenance (metadata.json), a README with instructions, and a prefix-versus-full recomputation check (recomputation-results.tsv).The quick workload uses static scale 1, stream scale 1, seed 42, 10 queries, generator maximum-query-size parameter 6, and one constant per query. It contains 56,915 static triples and 58,555 stream triples in 39,069 events. The larger workload uses static scale 10, stream scale 10, the same seed and query settings, and 50 queries. It contains 551,058 static triples and 4,849,758 stream triples in 3,708,693 events.
