Start at the factory, add PWA install and GPS real-world mode

The game now begins inside the Negin Sazan Pishgam Radmehr Atousa
vending-machine factory on the Mashhad–Chenaran road, and the world
extends ~20 km along the real driving route to Park Mellat and
Ferdowsi University.

- Factory compound: production hall with assembly line, office, yard,
  gate and company signs; first mission at its half-price demo machine
- Map data merged from four OSM extracts (factory zone, route corridor,
  region main roads, city zone), clipped to a 15 x 18 km region
- City meshes chunked and culled by distance; traffic recycled around
  the player; minimap and city map drawn from cached tiles + overview
- The Robot Market robot no longer walks with the family: it comes out
  of a machine when they arrive, greets them with expression portraits
  and goes back inside when they leave
- PWA: manifest, icons from the robot avatar, offline service worker
  generated at build time, install button / iOS steps, update prompt;
  Vazirmatn font bundled instead of Google Fonts
- Real-world mode: safety notice, GPS + compass tracking with accuracy
  smoothing, 20-40 m arrival radius, speed lock and in-person bonus
