feat: add initial Pokémon map data and loader

- Introduced a new JSON file `map_pokemon_v1.json` containing detailed city data for the Pokémon map, including attributes like population, agriculture, commerce, and connections.
- Implemented a map loader in `mapLoader.ts` to read and parse map definitions from JSON files, allowing for dynamic loading of map data.
- Created a script `generate-map-data.mjs` to convert legacy PHP map data into the new JSON format, ensuring compatibility with the updated map system.
