- Fix startRetrying to immediately perform first retry
- Adjust retry scheduling conditions
- Fix delay calculation for exponential backoff

Still debugging test failures

- Fix attemptCount to represent attempts started, not completed
- Fix exponential backoff delay calculation
- Fix retry scheduling conditions for proper max attempts handling
- All 10 useRetry tests now pass
- No regressions in existing test suite

Implements correct behavior:
- attemptCount increments when retry starts
- Exponential backoff: 1s, 2s, 4s, 8s, 16s, 30s (capped)
- Respects maxAttempts limit
- Manual retry cancels automatic retries
- State resets properly on success
