Subject: [PATCH] feat(defaults): apply RSocket's battle-tested configurations

- Add DEFAULT_CACHE_MAX_KEYS with limits per store type (prevents memory leaks)
- Add RETRY_BACKOFF_DELAYS [1s, 2s, 5s, 10s, 20s] for exponential backoff
- Add RETRY_JITTER_FACTOR (0.15) to prevent thundering herd
- Change INITIAL_PREKEY_COUNT from 812 to 30 (safer for rate limiting)
- Change MIN_UPLOAD_INTERVAL from 5s to 60s (avoids rate limiting)
- Change syncFullHistory default to false (conservative approach)

Based on RSocket fork's production-tested configuration.
