Add version group entry with region_id 0 (no PokeAPI region) and region

manually provided data won't be overwritten by re-runs. Includes
placeholder data file and box art.

Replaces the Python fetch_pokeapi.py script with a Go tool that crawls
a local PokeAPI instance and writes seed JSON files. Supports caching
and special encounter definitions via JSON config.
