Honour StreamOptions.headers in the Bedrock provider by attaching a
Smithy build-step middleware that merges caller headers into the
request before SigV4 signing. Reserved headers (x-amz-*, authorization,
host) are silently skipped to preserve signing and the bearer-token
auth path. No-op when no headers are supplied. Updates the
StreamOptions.headers JSDoc to drop the Bedrock caveat.
