🤖 Fix token limit error test to disable auto-truncation

The existing token limit error test was failing because auto-truncation
is now enabled by default for OpenAI, preventing the expected context
errors from occurring. This commit adds disableAutoTruncation: true to
that test to preserve its original behavior.
