Professional City Advisor rewrite + wall-clock simulation

Advisor v2:
- Phased policy (founding/village/town/city) with scaling reserves
- Maximal-coverage siting: services score candidate spots by count of
  previously-uncovered developed buildings in radius
- RCI gradient genesis: homes north, commerce buffering, industry
  set back 2 extra tiles; per-tile separation filters on new districts
- District placement scored by runway length and distance from housing
- Power sized to PROJECTED demand (history-smoothed growth x14 months)
  with tech diversity cap (<=3 per type) and home-distance scoring
- Collector roads: cluster orphaned plots, one straight L-path
- Budget discipline: one big-ticket purchase max per pass

Simulation core:
- City clock now advances in wall time (tick-guard bounded), decoupled
  from render fps — slow devices no longer freeze the city
- Smoke test polls in game-time (monthIndex targets), not wall time
