jpmschweitzerandClaude Sonnet 4.6 fb87f933f5 feat(simulation): add economics simulation binary with Layer 1+2 (#806, #807)
Adds tooling/econ-sim — a standalone Rust binary for the Phase 2 economics
simulation:

Layer 1 (Leontief production, #806):
- Deterministic per-run PRNG seeding of corp×site productivity (D-176)
- Fixed-coefficient production chains; scarcity cascades downstream (D-178)
- Per-capita population demand for finals and services
- Gate-energy demand reduction for fusion_fuel at connected nodes (D-186)
- Price adjustment via local tâtonnement

Layer 2 (spatial price equilibrium, #807):
- Damped tâtonnement trade flows along gate links (α=0.03, β=0.4, D-178)
- 8% transport cost per hop damps long-distance arbitrage
- Flows computed from pre-step snapshot; applied atomically
- --stability-check implements D-179 Tests 1 and 2:
  · Test 1: cold-start convergence ±5% at tick 100 → PASS (max 1.05%)
  · Test 2: long-run stability ±2% over ticks 900–999 → PASS (max 0.00%)
