Converts an interaction_policy map to a list of {circle_name, role} tuples.

Only known verbs and circles are included. Supports multiple circles per verb. Looks up followers/following URLs from the actor object if present.

Handles the special case: if automaticApproval contains only the author's identifier, this means "nobody can" and emits a negative role for all local users.

Examples

iex> interaction_policy = %{
...>   "canLike" => %{"automaticApproval" => ["https://www.w3.org/ns/activitystreams#Public"]},
...>   "canReply" => %{"automaticApproval" => "https://example.org/users/someone/followers"},
...>   "canQuote" => %{"automaticApproval" => "https://example.org/users/someone"}
...> }
iex> ap_incoming_interaction_policy_to_circle_roles(activity, interaction_policy)
[ {:guest, :react}, {:followers, :participate}, {:local, :cannot_critique} ]
