/**
 * AWS Bedrock — managed access to foundation models on AWS infrastructure.
 *
 * v1 supports **Anthropic Claude models on Bedrock** (the dominant case on
 * AWS). Other model families on Bedrock (Llama, Nova, etc.)
 * surface a clear error pointing at the supported set — they can be added in
 * follow-up PRs as demand justifies.
 *
 * Auth uses the standard AWS credential chain: env vars (`AWS_ACCESS_KEY_ID`,
 * `AWS_SECRET_ACCESS_KEY`, `AWS_SESSION_TOKEN`), IAM roles on EC2/ECS/Lambda,
 * `~/.aws/credentials`, etc. We don't accept credentials in `BedrockConfig` —
 * use environment-aware credentials so the same code works in dev and prod.
 *
 * Model strings:
 *   `bedrock/anthropic.claude-3-5-sonnet-20241022-v2:0`
 *   `bedrock/anthropic.claude-3-5-haiku-20241022-v1:0`
 *
 * @example
 * ```ts
 * // config/ai.ts
 * providers: {
 *   bedrock: {
 *     region: env('AWS_REGION', 'us-east-1'),
 *   },
 * }
 * ```
