Code Review

This pull request reduces the default maxAttempts for the retryWithBackoff utility from 10 to 3. This change significantly shortens the maximum potential wait time for operations that encounter repeated transient errors, improving the user experience by failing faster. The previous default could lead to waits of over 3 minutes, while the new default will fail after approximately 15 seconds. The accompanying test files have been updated accordingly to reflect this new default behavior. The changes are correct and self-contained.
