docs(readme): highlight dual RDF + LPG graph storage support

Semantica already ships both an RDF triplet-store stack (Blazegraph,
Apache Jena, Eclipse RDF4J via a unified TripletStore/SPARQL interface)
and an LPG graph-store stack (Neo4j, FalkorDB, Apache AGE, AWS Neptune
via Cypher), but the README only surfaced the LPG side. Add a hero
highlight line, a "What Semantica gives you" bullet, and split the
Features-at-a-Glance table row so both formats and all backends are
named explicitly.
