Drop-in replacement for WebSocket-based PeerManager and StateSync
using Braid-HTTP subscriptions. Key components:
- BraidPeerManager: HTTP-native peer transport (no WebSocket server)
- BraidStateSync: Push-based sync instead of polling
- BraidStatePublisher: Serves JSON state to Simpleton light clients
- SimpletonClient: Zero-CRDT read-only client (~50 lines of protocol)
