/**
* An activity transformer that assigns a new random ID to an activity if it
* does not already have one.  This is useful for ensuring that activities
* have an ID before they are sent to other servers.
*
* The generated ID is an origin URI with a fragment which contains an activity
* type name with a random UUID:
*
* ```
* https://example.com/#Follow/12345678-1234-5678-1234-567812345678
* ```
*
* @template TContextData The type of the context data.
* @param activity The activity to assign an ID to.
* @param context The context of the activity.
* @return The activity with an ID assigned.

/**
* An activity transformer that dehydrates the actor property of an activity
* so that it only contains the actor's URI.  For example, suppose we have an
* activity like this:
*
* ```typescript
* import { Follow, Person } from "@fedify/vocab";
* const input = new Follow({
*   id: new URL("http://example.com/activities/1"),
*   actor: new Person({
*     id: new URL("http://example.com/actors/1"),
*     name: "Alice",
*     preferredUsername: "alice",
*   }),
*   object: new Person({
*     id: new URL("http://example.com/actors/2"),
*     name: "Bob",
*     preferredUsername: "bob",
*   }),
* });
* ```
*
* The result of applying this transformer would be:
*
* ```typescript
* import { Follow, Person } from "@fedify/vocab";
* const output = new Follow({
*   id: new URL("http://example.com/activities/1"),
*   actor: new URL("http://example.com/actors/1"),
*   object: new Person({
*     id: new URL("http://example.com/actors/2"),
*     name: "Bob",
*     preferredUsername: "bob",
*   }),
* });
* ```
*
* As some ActivityPub implementations like Threads fail to deal with inlined
* actor objects, this transformer can be used to work around this issue.
* @template TContextData The type of the context data.
* @param activity The activity to dehydrate the actor property of.
* @param context The context of the activity.
* @returns The dehydrated activity.
* @since 1.4.0
