Use an exponential delay for API retries

[mrubens]

#426

---

Important

Implement exponential backoff for API retries in Cline.ts with updated tests in Cline.test.ts.

• Behavior:
  • Implement exponential backoff for API retries in attemptApiRequest() in Cline.ts.
  • Retry delay is calculated as baseDelay * 2^retryAttempt.
• Tests:
  • Update Cline.test.ts to test exponential backoff logic.
  • Verify countdown messages and delay calls for retries.
  • Ensure retry logic is triggered on initial API failure.

@mrubens Is there a way to make it so this mechanism is opt-out optional so the traditional method we used is still accessible?
