V2: bring Bedrock Converse native auth and config to parity #34997
Description
Context
Native Bedrock Converse exists, but it does not yet match AI SDK plugin behavior for common AWS credential and region setups.
Scope
- Add default AWS credential chain/profile/container credential behavior where appropriate.
- Support Bedrock bearer token environment behavior.
- Review region, endpoint override, cross-region inference profiles, guardrails, performance config, and model-specific request fields.
- Keep Converse separate from Mantle.
Acceptance Criteria
- Common AI SDK Bedrock auth/config paths have native equivalents.
- Runner/catalog mapping can safely choose native Bedrock Converse for supported models.
- Recorded or fixture tests cover credential-chain and request-shape behavior.

Mostly done: native Bedrock now uses the AWS default credential chain with profiles (#47436), bearer token auth, credential discovery (#47548), an AWS profile picker (#53626) and inference-profile IDs (#48078, #54486). Still missing:
guardrailConfigandperformanceConfigpassthrough in bedrock-converse. Closing this tracker. If those are needed, a focused issue for them is easier to pick up.
