feat: Docker realization, node binary, docs reorg, and simulation testing
Docker realization (bridging simulation to real TCP):
- NodeDriver (`crates/distribution/src/driver.rs`): bridges DistributedNode
tick loop to TcpTransport with piggyback-extended wire messages
- swactor-node binary (`crates/node/`): CLI node with --listen, --seed,
--dashboard-port, --actors flags
- Dockerfile: multi-stage build (rust:1.93-slim → debian:bookworm-slim)
- Docker integration tests (`tests/docker/`): 5-node cluster with 4
scenarios (convergence, failure detection, actor resolution, rejoin)
- LAN cluster scripts for cross-machine validation
- TCP transport retry-on-stale-connection logic
- /api/distribution REST endpoint on dashboard (feature-gated)
- Piggyback fields (piggyback + from_addr) on Ping/Ack/PingReq messages
Docs reorganization:
- docs/runtime/ — actor-model, runtime, worker-thread, channels
- docs/distribution/ — distribution, swim, kademlia, transport
- docs/diagrams/ — all SVG files
- docs/connectome/ — connectome analysis
- docs/development_history/ — DOCKER_REALIZATION.md, SIMULATION_TESTING.md
- render_docs.sh outputs to docs/diagrams/
- README links updated to new paths
