Follow-up bedrock-runtime positioning updates in Quickstart and model cards
Follow-up updates continuing the <code class="code">bedrock-runtime</code> positioning work. Reordered the code sample tabs on the <a href="https://docs.aws.amazon.com/bedrock/latest/userguide/getting-started.html">Quickstart</a> page to lead with the Messages API, followed by the Responses, Chat Completions, Converse, and Invoke APIs. The Messages API tab now targets the <code class="code">bedrock-runtime</code> endpoint using the <code class="code">AnthropicBedrock</code> client (AWS SigV4 auth), so all Quickstart tabs consistently use <code class="code">bedrock-runtime</code>. Updated the Quickstart code samples to use Claude Opus 5 for Anthropic and GPT-5.6 Sol for OpenAI. Added a suggestion callout under the Model Details section of every model card that supports <code class="code">bedrock-runtime</code>, recommending the <code class="code">bedrock-runtime</code> endpoint for new applications. Added Daybreak Red: GPT-5.6 Cyber and Daybreak Blue: GPT-5.6 Sol to the OpenAI row of the <a href="https://docs.aws.amazon.com/bedrock/latest/userguide/model-cards.html">Models at a glance</a> summary table.
