Help the user implement an ActivityPub actor using Fedify.

Walk through:

1.  Registering `setActorDispatcher(path, handler)` on the `Federation`
    object or `FederationBuilder`, including the `{identifier}` path
    parameter.
2.  Returning a `Person`, `Service`, or other `Actor` vocabulary object
    with the required fields (`id`, `inbox`, `publicKey`, etc.).
3.  Chaining `.setKeyPairsDispatcher()` to supply RSA and Ed25519 keys.
4.  Optionally configuring `mapActorAlias()` for handle-based or
    fixed-path aliases.
5.  Making the actor discoverable via WebFinger. Fedify handles
    `/.well-known/webfinger` automatically once the actor dispatcher
    is registered.
