Certificate verification errors bypass session retry #37884
Description
Description
When a provider request fails with unknown certificate verification error, the error is classified as UnknownError. It therefore bypasses the existing session retry policy and stops the turn, even when the failure is transient.
The certificate verification failure should enter the same retry path as other retryable transport errors. This issue is limited to retry classification; #36590 separately covers improving the user-facing error message.

Steps to reproduce
- Start a provider request.
- Trigger a transient connection failure that surfaces as
unknown certificate verification error. - Observe that the session stops instead of entering retry state.
