Subject: [PATCH] fix: correct Grok-4-Fast pricing and maxTokens according to
 official xAI specs

- Fix inputPrice from .0 to /bin/sh.20 per million tokens
- Fix outputPrice from .0 to /bin/sh.50 per million tokens
- Update maxTokens from 30,000 to 8,192 (matching grok-4, as xAI doesn't publish max output limit)
- Remove subjective 'SOTA cost-efficiency' wording from description
