What's Changed

Anthropic Beta Headers Configuration Update

This patch syncs the anthropic_beta_headers_config.json from main, bringing two key improvements:

1. Enabled context-1m-2025-08-07 beta header for Anthropic and Vertex AI

• Previously this header was disabled (null) for both the anthropic and vertex_ai providers
• Now correctly passes through the context-1m-2025-08-07 beta header, enabling support for Anthropic's 1M context window feature when requested by clients

2. Added Databricks provider beta header mappings

• Added a complete set of Anthropic beta header mappings for the databricks provider, enabling Databricks-hosted Anthropic models to correctly forward beta feature headers including:

Impact

• The 1M context window beta feature now works correctly on both direct Anthropic and Vertex AI providers
