feat: add strategic synthesis layer — Phase 11 (+4 = 68 tools)

- intel_strategic_posture: composite risk from 9 weighted domains
  (military, political, conflict, infrastructure, economic, cyber,
  health, climate, space) with per-domain scoring and top threats
- intel_world_brief: structured daily intelligence summary aggregating
  posture, focal points, news clusters, anomalies, trending threats
- intel_fleet_report: naval fleet activity combining theater posture,
  waterway status, military surge, and readiness scoring
- intel_population_exposure: population at risk near active events
  (earthquakes, wildfires, conflict) using 105-city dataset (1B pop)

New files: analysis/posture.py, analysis/world_brief.py,
analysis/exposure.py, sources/fleet.py, config/population.py
