feat(backend): Add agent tokens endpoints

[tmilewski]

Description

Adds support for the Agent Tokens API endpoint to the backend SDK. This allows developers to create agent tokens that can be used to impersonate users during testing or other automated flows.

Usage

import { createBackendApiClient } from '@clerk/backend';

const client = createBackendApiClient({ secretKey: 'sk_test_...' });

// Create an agent token
const agentToken = await client.agentTokens.create({
  userId: 'user_xxx',
  sessionMaxDurationInSeconds: 1800, // optional
});

// Access token properties
console.log(agentToken.token);
console.log(agentToken.url);
console.log(agentToken.status); // 'pending' | 'accepted' | 'revoked'

📝 Walkthrough

Walkthrough

Adds Agent Tokens support to the backend SDK: a new AgentTokenAPI endpoint with a create method that POSTs to /agent_tokens, a new AgentToken resource model with fields (id, userId, token, status, url, createdAt, updatedAt), JSON schema (AgentTokenJSON) and ObjectType.AgentToken, deserialization handling for AgentToken, and re-exports to the public API surface. Includes a changeset marking a minor version bump for the backend package.
