In-process consumers only for now; a shipped reference driver replaces the ad-hoc scripts

 - **Rivers and mountain ranges now have names behind the map** (T-1169) — every body's rivers and peaks are assigned names from the curated per-system pools (17,891 names across the Reach) during world generation, queryable over the wire.
