docs(bankr): weekly skill update — May 9–16

[sidrisov]

Summary

Weekly sync of the bankr skill with recent platform changes (May 9–16).

• LLM Gateway — Grok 4.3: Add xAI Grok 4.3 to the model catalog (1M context, image input, value-tier pricing). Update provider descriptions to mention Grok alongside Claude, Gemini, and GPT.
• Per-automation model selection (Max Mode): Automations can now run with a specific LLM model instead of the wallet default. New section in references/automation.md covers configuration, LLM credit consumption, and out-of-credits behavior.
• x402 security model update: The per-app daily spend cap has been removed. Each x402 call now requires explicit user approval via a confirmation modal showing the probed price — updated the capability description accordingly.
