NASA POWER ingest: heal NULL fields, request precip, respect 2-day lag

Make fork-and-adapt flow truly region-agnostic

Add print/flush logging to ingestion for HF debugging

Cut ERA5-Land from live pipeline, fix zone count to 15 Dar zones

Deduplicate NASA POWER requests by grid cell (15 zones → 2 API calls)

Fix pipeline: Dar-only zones, ERA5-Land date range fallback

Fix critical pipeline bugs, purge flood-era code, add ERA5 to Dockerfile

Switch pipeline ingestion to ERA5-Land (9km), NASA POWER as fallback

Add LSTM neural model, ERA5 data, FAISS+BM25 RAG, Neon DB, eval suite; de-jargon frontend
