chore: improve visz on 504: Error in partition - {"error": "Connection error while initiating partition request from unstructured_client", "message": "", "type": "partition_connection_error"} (#338)

504: Error in partition - {"error": "Connection error while initiating
partition request from unstructured_client", "message": "", "type":
"partition_connection_error"}


change: "ReadError after 5 retries over 312.4s" instead of "message": ""

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Behavior only changes error formatting/raising when the backoff budget
is exhausted; normal retry and success paths are unchanged.
> 
> **Overview**
> Improves observability when retries exceed `max_elapsed_time` by
rethrowing the original exception type with a message that includes the
number of attempts and total elapsed time (sync and async backoff
paths), while preserving the original exception via chaining.
> 
> Bumps the generated SDK version/user-agent from `0.43.2` to `0.43.3`.
