fix(retry): resolve RETRY_BACKOFF_DELAYS initialization order error

- Remove duplicate RETRY_BACKOFF_DELAYS and RETRY_JITTER_FACTOR from Defaults/index.ts
- Export constants from retry-utils.ts as single source of truth
- Add 'as const' for better type inference
- Fixes "Cannot access 'RETRY_BACKOFF_DELAYS' before initialization" error
