Add health checks (/healthz), Prometheus metrics export (/metricsz),
and tracing spans to the P2P mesh node. MeshNode.run() starts GC and
health server as background tasks, returning a RunHandle for lifecycle
management. Health endpoint returns 503 during graceful shutdown drain.
Completed in this session:
- KeyPackage distribution over mesh (announce-based)
- Transport capability negotiation
- MLS-Lite to full MLS upgrade path
Updated mesh-protocol-gaps.md to reflect completed items.
Implement transport abstraction (TCP/iroh), announce and routing table,
multi-hop mesh router, truncated-address link layer, and LoRa mock
medium with fragmentation plus EU868-style duty-cycle accounting.
Add mesh_lora_relay_demo and scripts/mesh-demo.sh. Relax CBOR vs JSON
size assertion to match fixed-size cryptographic overhead. Extend
.gitignore for nested targets and node_modules.
