Atlas Digest: a daily "what changed in 24h" round-up for journalists + AI labs

Single-call pre-rendered daily summary at /v1/atlas/digest (JSON) and /v1/atlas/digest.html (email-friendly). Eight sections: new incidents in last 24h, forecast movers (>10pp), DBSCAN anomalies, multi-country blocked domains, lead/lag triggers, active-learning queue top-3, cross-source agreement rate, and model-drift watch. Built daily at 04:30 UTC by scripts/build-atlas-digest.py and served as a flat sidecar (no per-request compute). Honest caveat baked in: this is a SNAPSHOT — the live channel is the /v1/incidents/stream SSE feed.
