Anu.Client (Anu v0.2.1)

An explicit client holding the credentials and settings used to deliver messages and call anu_cloud.

Anu never reads application env for delivery and never starts its own Finch instance: you bring a Finch name (started in your own supervision tree) and the credentials for each WhatsApp phone number / WABA.

Build one client per phone number / WABA to run multiple numbers or multiple access tokens in the same BEAM node:

# In your application supervision tree:
#   {Finch, name: MyApp.Finch}

support = Anu.Client.new(finch: MyApp.Finch, access_token: "EAAG...", phone_number_id: "111")
sales   = Anu.Client.new(finch: MyApp.Finch, access_token: "EAAG...", phone_number_id: "222")

Anu.Message.new("+5511...")
|> Anu.Message.text("hi")
|> Anu.deliver(support)

Credentials (:access_token, :phone_number_id, :cloud_api_key) may be nil until use; adapters raise at delivery time when they are missing.
