Pull Request Overview

This PR enhances the polling loop in the HTTP/1 client dispatcher to avoid premature yielding when there's still write work to be done. The key change ensures that when a body is being written and the connection becomes ready after flushing, the loop continues instead of yielding, which would cause a deadlock if no reads are expected.

Key changes:

• Capture the flush readiness state to determine if more write work can be done
• Introduce wants_write_again logic to check if body writing should continue
• Update the loop exit condition to consider both read and write readiness
