In `@llm/pricing_registry.json`:
- Around line 2300-2320: Add Bedrock registry entries for gpt-6-astra covering
the global.openai.gpt-6-astra and us.openai.gpt-6-astra model IDs, preserving
the existing GPT-6 Astra token limits, capabilities, prices, and
contextPriceTiers from the providers.openai record so GetModelInfo resolves
Bedrock requests.
