Use IGDB_CLIENT_ID/SECRET env var names directly

For clarity in HuggingFace Spaces configuration, use the same
environment variable names that the IGDB MCP server expects.

Set these secrets in HF Spaces settings:
- IGDB_CLIENT_ID (your Twitch Client ID)
- IGDB_CLIENT_SECRET (your Twitch Client Secret)
