Adds a Grok (xAI) provider fetcher to the dashboard's usage aggregation so a Grok card now appears in the Usage dropdown when credentials are configured.
- Add fetchGrokUsage() in usage.ts: resolves the API key from GROK_API_KEY env, then ~/.grok/user-settings.json, then grok-cli auth storage, and validates it against GET https://api.x.ai/v1/api-key
- Since xAI exposes no subscription usage meter for inference keys, the card reports auth-validity status (ok/no-auth/error) with an empty usage-window list rather than fabricating quota data
- Surfaces clear error messages for expired/blocked keys and non-200 responses; omits the card entirely when no credentials are found
- Register fetchGrokUsage in fetchAllProviderUsage's parallel provider fetch list alongside Claude, Codex, Gemini, Minimax, Zai, and GitHub Copilot
- Add extensive test coverage in usage.test.ts for key-source precedence, ok/error/no-auth states, and blocked/expired key handling
- Add changeset (.changeset/fn-7814-grok-usage.md) documenting the new minor feature
