Incomplete grok-4.6 model definition

High Severity

The new xai.grok-4.6 entry is a stub: mode is unknown, costs list only us-west-2 with no token prices, and extra_configuration.bedrock_mantle_adhoc_prefix is missing. Grok on Mantle is a chat model served under /openai, so the registry will publish the wrong mode, omit pricing, and route requests to the plain /v1 path instead of /openai/v1.
