[data] Commit countries_enriched.json so the app/Space is ready without the pipeline

The enriched stats overlay (227 KB) was gitignored as a regenerable artifact, but
committing it means prod (and the HF Space) has full country stats immediately,
with no need to run enrich_downloader.py. The 23 MB RAG index stays out of git and
is uploaded to the Space via 'hf upload' (LFS). country_lookup still falls back to
the curated countries.json if either is absent.
