Ice Block curated packs

Nova Opus by Mateza. Authors: Mateza Kayondo and Promesse Rukundo.

Small curated English↔Kinyarwanda JSONL packs used to thicken Ice Block basics (primer / greetings / drills) for v5.5 — not the full ~1.28M lake dump.

Why these packs

Lake audit: ~1.28M pairs were mostly general/legal; primer+greetings were ~0.16%. Later NLLB-heavy continues lost to champion v5.2 (capability en-rw 21/22). Prefer curated basics over more mined mass. After v5.5 curated ingest (live): primer 4,582, greetings 162.
