Initial MVP: drivable RX-7 vertical slice + server-authoritative systems

- Rojo + Wally project; ProfileStore (loleris) for safe saves
- Shared: GameConfig, Cars (RX-7 free starter), ProfileTemplate, Remotes
- Server: DataManager, Economy, CarManager, RaceManager, MapBuilder, AntiCheat
- Client: neon HUD + Garage/Dealership UI (buy/equip/upgrade), race/daily
- Procedural Tokyo expressway (spawn pad, finish line, neon pylons, kill walls)
- CI workflow (Gitea/GitHub), Makefile, selene+stylua clean, rojo builds
- Docs: README, GDD, realistic solo ROADMAP
