@spec awake(Wardrik.t(), String.t()) :: {:ok, pid()} | {:error, Wardrik.Error.t()}

Returns the agent id, waking it from its definition if needed, or a not_found error.

@spec bring(Wardrik.t(), keyword()) :: {:ok, pid()} | {:error, Wardrik.Error.t()}

Starts the agent opts describe, or reconfigures it if it's running.

A running agent uses the new options from its next turn. A saved agent uses them as it loads.

@spec definable(String.t()) :: :ok | {:error, Wardrik.Error.t()}

Returns :ok if the agent id can have its own definition. Conversations can't.

@spec definition(Wardrik.t(), String.t()) ::
  {:ok, map()} | {:error, Wardrik.Error.t()}

Returns the agent id's definition, or a not_found error. A conversation uses its agent's.

@spec known?(Wardrik.t(), String.t()) :: boolean()

Returns whether the agent id is running, saved or defined.

@spec whereis(Wardrik.t(), String.t()) :: pid() | nil

Returns the running agent id, or nil.
