[BOT ISSUE] Bedrock: add missing openai.gpt-6-astra (GPT-6 Astra)

[github-actions]

Summary

OpenAI's GPT-6 Astra launched on Amazon Bedrock on September 8, 2026 as openai.gpt-6-astra, but this Bedrock-specific model ID is missing from the catalog. The generic gpt-6-astra entry exists (line ~227) with available_providers: ["openai", "azure", "openrouter"] but does not include bedrock, and no Bedrock-format entry exists.

Multimodal	Yes (text + image input)	Bedrock model card — Modalities

Cross-source verification

• Confirmed on Bedrock model cards overview — listed under OpenAI provider as "GPT-6 Astra"
• Confirmed on Bedrock model card page — model ID openai.gpt-6-astra, pricing, context, regional availability, sample code
• Model ID format is consistent with existing Bedrock OpenAI entries (openai.gpt-5.6-sol, openai.gpt-5.6-terra, openai.gpt-5.6-luna, openai.gpt-5.6-cyber, etc.)
• Not present in model_list.json (grep for openai.gpt-6-astra returns zero matches)

Additional context

• Pricing note: Bedrock In-Region pricing includes 10% markup over direct OpenAI rates ($10/$50 direct → $11/$55 Bedrock), consistent with other Bedrock OpenAI entries (e.g., openai.gpt-5.6-sol is $4.4/$22 vs $4/$20 direct)
• Long context pricing: >272K input tokens: $22/$82.50/$2.20/$27.50 (separate tier, may warrant a note or separate entry like the short-context openai.gpt-5.6-sol pattern)
• Cross-region IDs: us.openai.gpt-6-astra (geo) and global.openai.gpt-6-astra (global) inference profiles exist but no other Bedrock OpenAI models have us.* or global.* entries — these can be deferred
• Generic entry update: The existing gpt-6-astra (line ~227) should also get "openai.gpt-6-astra" added to its fallback_models and/or bedrock added to available_providers
• Available on bedrock-mantle (us-west-2 in-region) and bedrock-runtime (US geo, global cross-region)
• Supports Responses API, Chat Completions API, and Converse API
• Model lifecycle: Active, launched Sep 8, 2026, EOL no sooner than Sep 8, 2027
