- Added @waku/sds dependency
- Created MinimalSDSWrapper for basic causal ordering
- Enhanced vote messages with SDS metadata (Lamport timestamps, causal history)
- Updated MessageManager to use SDS for vote conflict resolution
- Added SDS status indicator in header
- Added debug logging for SDS operations
This is a minimal proof-of-concept that:
- Uses a single SDS channel for all votes
- Only applies to vote messages (other message types unchanged)
- Maintains backward compatibility
- Can be disabled by removing the SDS enhancement
