Macula Application Root Supervisor.

This is the top-level supervisor for the Macula application. It manages all Macula subsystems in an always-on architecture.

Supervision Hierarchy (v0.8.5+):

  macula_root (this module - application root)
  ├── macula_routing_server (core DHT infrastructure - always on)
  ├── macula_bootstrap_system (bootstrap services - always on)
  │   ├── macula_bootstrap_server
  │   ├── macula_bootstrap_registry
  │   └── macula_bootstrap_health
  ├── macula_gateway_system (gateway services - always on)
  │   ├── macula_gateway_health
  │   ├── macula_gateway_diagnostics
  │   ├── macula_gateway_quic_server
  │   ├── macula_gateway
  │   └── macula_gateway_workers_sup
  ├── macula_bridge_system (hierarchical mesh bridging - optional)
  │   ├── macula_bridge_node (parent mesh connection)
  │   ├── macula_bridge_mesh (peer bridge mesh)
  │   └── macula_bridge_cache (parent query results cache)
  ├── macula_peers_sup (dynamic peer connections - always on)
  └── macula_platform_system (platform layer - always on)
      ├── macula_leader_election (deprecated - scheduled for removal v0.14.0)
      └── macula_crdt (LWW-Register, OR-Set in v0.14.0)
  

Architecture Philosophy (v0.8.5): - All nodes have ALL capabilities (no mode selection) - Zero configuration required (TLS auto-generated) - Simplified deployment (every node is bootstrap + gateway + peer) - True P2P mesh (nodes connect on-demand based on capability discovery)

Naming Convention (v0.7.10+): - _root: Application root supervisor (one per application) - _system: Subsystem root supervisors (gateway, peer, bootstrap, etc.) - _sup: Worker supervisors (workers_sup, peers_sup)
