Auto-Build advisor + resilient simulation loop

Browse Source 
- New advisor button (toolbar, purple wand): one click per planning pass
  * Genesis: founds a town from a blank map (main street + zone bands)
  * Keeps power ahead of demand (wind/solar/coal by deficit size)
  * BFS road spurs to reach orphaned zoned land
  * Stamps new districts when demand is high and empty plots run out
  * Places the weakest service coverage; parks/plazas for land value
  * Never spends below an emergency reserve; recomputes power per action
- Simulation no longer dies when rAF throttles: interval watchdog
  compensates only after 3s of total frame silence
- preserveDrawingBuffer now opt-in via ?cap=1 (software-GL perf)
- Smoke test drives via game API, prefers headless_shell binary,
  tolerates stalled screenshots; engine suite at 51 assertions
