Supervisor for WebSocket adapters with fault tolerance.

This supervisor manages adapter GenServers alongside the ClientSupervisor, creating a robust supervision tree where:

• ClientSupervisor manages Client GenServers
• AdapterSupervisor manages adapter GenServers
• Adapters monitor their Clients and handle reconnection

Example

children = [
  {ZenWebsocket.ClientSupervisor, []},
  {ZenWebsocket.Examples.AdapterSupervisor, [
    adapters: [
      {DeribitGenServerAdapter, [
        name: :deribit_main,
        client_id: "...",
        client_secret: "..."
      ]},
      {DeribitGenServerAdapter, [
        name: :deribit_backup,
        url: "wss://www.deribit.com/ws/api/v2",
        client_id: "...",
        client_secret: "..."
      ]}
    ]
  ]}
]
