Module bedrock_provider 

Native AWS Bedrock (Amazon Titan) embedding provider (sync ureq + SigV4). AWS Bedrock embedding provider (Amazon Titan) over the InvokeModel REST API.

Deliberately dependency light: a synchronous ureq call plus a small hand-rolled SigV4 signer, so the engine gains native Bedrock support without pulling in the full async AWS SDK. This matches the lean, no-heavy-deps philosophy of the rest of the engine (see the http provider).

Credentials come from the standard AWS environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_SESSION_TOKEN for temporary/SSO credentials). Full credential-chain resolution (profiles, instance metadata) is intentionally out of scope for this provider; export credentials or use the platform’s SDK-backed path for those.
