`python -m gaming_deals_bot --check` tests each external dependency
before starting the bot:
- Matrix: verifies access token (whoami) and room membership
- CheapShark: hits the deals endpoint
- Epic Games Store: hits the free-games endpoint
- Frankfurter: fetches exchange rates
- IsThereAnyDeal: validates the API key (skipped if not set)
Exits 0/1 so it works in CI pipelines and Docker health-checks.
