map: rebuild circuit on real Shuto C1 geometry from OpenStreetMap

Browse Source

Replace the invented rounded-rectangle circuit with the actual Shuto
Expressway Inner Circular Route (relation 4256008) traced from OSM and
projected to studs at 1 stud = 0.28 m.

- Circuit.luau: 823 evenly-spaced samples (60 studs), 49,388 studs /
  13.83 km lap. Real junction names (Tanimachi, Miyakezaka, Kasumigaseki,
  Ginza, Kyobashi, Edobashi, Hitotsubashi), real tunnel + viaduct
  sections. Deck height smoothed to max 4.3% grade.
- MapBuilder.luau: builds road, guardrails, kill walls, lit tunnel bores,
  viaduct pillars, junction gantry signs, Daikoku-style PA, and Tokyo
  landmarks (Tower, Skytree, Imperial Palace moat, Station, Ginza,
  Shiodome, Roppongi Hills, National Diet) at true relative positions.
- Contract names (SpawnPad, FinishLine, KillWall) unchanged, so gameplay
  code is untouched.
