fix(amazon-bedrock): disable native structured output for claude-opus-4-7

[zxuhan]

Summary

Fixes #14773.

Bedrock rejects output_config.format for claude-opus-4-7 (including the us./eu. cross-region inference profiles) with:

output_config.format: Extra inputs are not permitted

packages/amazon-bedrock/src/anthropic/amazon-bedrock-anthropic-provider.ts previously hardcoded supportsNativeStructuredOutput: true for every Bedrock-Anthropic model. The Anthropic capability table already lists opus-4-7 as supporting structured output, so the SDK took the native path that Bedrock then refused, and any output / Output.object(...) call against opus-4-7 (including reasoning runs) failed before the model ran.

This changes the flag to !modelId.includes('claude-opus-4-7'). Other Bedrock-Anthropic models stay on the native path; opus-4-7 falls back to the jsonResponseTool path, which Bedrock accepts. Using includes() covers the direct anthropic.claude-opus-4-7 id and both cross-region inference profiles (us.anthropic.claude-opus-4-7, eu.anthropic.claude-opus-4-7).

Test plan

• Added a parameterized test for the direct id and both cross-region prefixes. The existing default-model assertion still requires supportsNativeStructuredOutput: true for non-opus-4-7 models.
• pnpm --filter @ai-sdk/amazon-bedrock test: 369/369 pass (node + edge)
• pnpm check: lint and format clean
• pnpm --filter @ai-sdk/amazon-bedrock type-check

verified that the fix works for the following example

import { bedrockAnthropic } from '@ai-sdk/amazon-bedrock/anthropic';
import { generateText, Output } from 'ai';
import 'dotenv/config';
import { z } from 'zod';
import { run } from '../../lib/run';

run(async () => {
  const result = await generateText({
    model: bedrockAnthropic('global.anthropic.claude-opus-4-7'),
    output: Output.object({
      schema: z.object({
        recipe: z.object({
          name: z.string(),
          ingredients: z.array(
            z.object({
              name: z.string(),
              amount: z.string(),
            }),
          ),
          steps: z.array(z.string()),
        }),
      }),
    }),
    prompt: 'Generate a lasagna recipe.',
  });

  console.log('Recipe:', JSON.stringify(result.output, null, 2));
  console.log();
  console.log('Finish reason:', result.finishReason);
  console.log('Usage:', result.usage);
});

thanks!
