* feat: seed GDELT intelligence topics to Redis with bootstrap hydration
Add standalone seed script that pre-populates all 6 Live Intelligence
topics (military, cyber, nuclear, sanctions, intelligence, maritime)
from the GDELT Doc API into Redis. Frontend consumes bootstrap data
lazily via the service layer, falling back to RPC if unavailable.
- scripts/seed-gdelt-intel.mjs: new seed script with per-topic 429 retry
- api/bootstrap.js: register gdeltIntel in FAST_KEYS
- api/health.js: register in BOOTSTRAP_KEYS + SEED_META + dataSize
- api/seed-health.js: register in SEED_DOMAINS
- scripts/_seed-utils.mjs: add topics to recordCount detection
- src/services/gdelt-intel.ts: lazy bootstrap consumption in service layer
* fix(seed): align staleness thresholds and strengthen GDELT validation
- seed-health intervalMin 30→60 so staleness (120min) matches health.js maxStaleMin
- validate requires ≥3/6 topics populated (not just military)
- recordCount sums articles across topics instead of reporting topic count
