Update project config for Go tool and port change

Add Go to .tool-versions, update .gitignore for Go build output and
cache, document seed data regeneration in README, and change API port
from 8000 to 8080 in docker-compose.

+All code changes are complete. Run verification:
+1. Run the script to completion
+2. Verify output (pokemon.json has forms, correct IDs, etc.)
+3. Verify cache speedup on second run
+4. Frontend build check
+
+## Checklist
+- [ ] Run fetch_pokeapi.py to completion
+- [ ] Verify pokemon.json has more entries with forms (megas, gmax, regionals)
+- [ ] Verify pokeapi_id/national_dex split is correct
+- [ ] Verify route/encounter JSON files
+- [ ] Verify cache speedup on second run
+- [ ] Frontend build passes

 The local PokeAPI data repository we use as a submodule is outdated. It's missing data for newer Pokemon forms and potentially newer games.

+Rewrite the Python PokeAPI fetching tool in Go with custom HTTP client, disk caching, and zero external dependencies. Replace aiopoke dependency that crashes on newer PokeAPI fields.

+The seeder reads from pre-generated JSON files in `backend/src/app/seeds/data/` (committed to the repo) and loads them into PostgreSQL. No external API access is needed — everything runs from local files inside the container.

+
+### Regenerating Seed Data
+
+The seed JSON files don't normally need regenerating. If you need to update them (e.g., to pull in new PokeAPI data), run the Go fetch tool against a local PokeAPI instance:
+
+1. Start a local PokeAPI (e.g., using [pokeapi/pokeapi](https://github.com/PokeAPI/pokeapi)):
+
+   ```bash
+   # In a separate directory
+   git clone https://github.com/PokeAPI/pokeapi.git && cd pokeapi
+   docker compose up
+   ```
+
+   This serves the API at `http://localhost:8000/api/v2` by default.
+
+2. Run the fetch tool (requires Go 1.22+):
+
+   ```bash
+   cd tools/fetch-pokeapi && go run .
+   ```
+
+   Set `POKEAPI_URL` if your instance is at a different address:
+
+   ```bash
+   POKEAPI_URL=http://localhost:9000/api/v2 go run .
+   ```
+
+   Use `--clear-cache` to discard cached API responses and re-fetch everything.
+
+3. Review and commit the updated JSON files in `backend/src/app/seeds/data/`.
