Scope cut: drive-only MVP (remove racing + economy)

Per user direction, the MVP is now simply driving cars on the expressway.
- Removed RaceManager and Economy modules entirely
- Slimmed Remotes to DataUpdated / SpawnCar / EquipCar
- ProfileTemplate now just remembers the last driven car (v2)
- Cars: dropped price/rep/upgrade fields; kept identity + driving stats
- CarManager: stat-based tuning only; RX-7 allowlist via GameConfig.canDrive
- DataManager: assign default car on join; downgrade RX-7 if de-allowlisted
- Client: replaced garage/economy UI with a simple car picker + respawn
- Docs: GDD/ROADMAP/README rewritten for drive-only; added docs/MESH_SWAP.md
- Gates: stylua clean, selene 0/0, rojo builds

-race the neon Tokyo expressway, earn cash + rep, buy and upgrade faster cars.
+A Roblox game where you cruise a neon Tokyo expressway at night in cool cars —
+starting with a real 1993 Mazda RX-7. **This MVP is deliberately tiny: just
+driving.** No racing, money, or upgrades yet — the goal is to nail the driving
+feel and be testable fast. See `docs/ROADMAP.md` for what comes next.
 
-**Status:** Playable vertical slice. Drive → race → earn → save works end to end.
-Built code-first — there is nothing to hand-build in Studio to run it.

 | Module | Responsibility |
 |---|---|
-| `DataManager` | Wraps **ProfileStore** — session locking, reconcile, Studio mock. The data-safety foundation. |
-| `Economy` | The only place cash/rep/ownership change. Buy, upgrade, daily, race payouts. |
-| `CarManager` | Spawns the equipped car (VehicleSeat-driven placeholder) with upgrade-scaled tuning. |
-| `RaceManager` | Solo time-trial; server validates the finish-line touch before paying out. |
-| `MapBuilder` | Procedurally builds the expressway, spawn pad, finish line, neon pylons, kill walls. |

+The RX-7 demo-lock: `GameConfig.RX7AllowedUserIds` holds the owner's + son's
+Roblox UserIds; only they can select/drive the RX-7 (enforced in `CarManager` and
+the `EquipCar` remote).
 
 ## Replacing the placeholder RX-7 with the real mesh
 
-The car is currently a coloured block + `VehicleSeat` so the game is drivable today.
-When you import the real RX-7 model:
-1. Drop the mesh/model into `ReplicatedStorage` (or an assets folder).
-2. Rewrite only `CarManager.buildCarModel` to clone it and weld a `VehicleSeat`.
-3. Everything else (economy, upgrades, races, saving) keeps working unchanged.
