fix(defaults): address PR #10 code review feedback

- Integrate RETRY_BACKOFF_DELAYS and RETRY_JITTER_FACTOR into retry-utils.ts
  - Add retryConfigs.rsocket using the default delays
  - Add getRetryDelayWithJitter() helper function
  - Add getAllRetryDelaysWithJitter() for planning
- Document DEFAULT_CACHE_MAX_KEYS with usage example
- Adjust INITIAL_PREKEY_COUNT from 30 to 200 (moderate value)
- Adjust MIN_UPLOAD_INTERVAL from 60s to 10s (balance rate limiting/responsiveness)
- Revert syncFullHistory to true (avoid breaking change)
