## Summary This PR introduces a `HeaderProvider` which is called for all remote HTTP calls to get the latest headers to inject. This is useful for features like adding the latest auth tokens where the header provider can auto-refresh tokens internally and each request always set the refreshed token. --------- Co-authored-by: Claude <noreply@anthropic.com>
