Using https://docs.zernio.com, complete the following task:

Using Zernio, build me a script that prepares a launch announcement as a draft post without publishing anything:

1. Install and use the official Zernio SDK if one is available; otherwise use the documented REST API
2. Create a new profile, brand, or workspace named "arena-<current unix timestamp>" to hold the post. If Zernio has no such concept, use the account's default one and say so
3. List the social accounts connected to it and print how many there are (it is fine if there are none)
4. Save this text as a draft post that is neither scheduled nor published:
   "We just shipped v2 of our API: faster uploads, signed webhooks and a new Python SDK. #devtools"
5. Read the draft back by its id, then append " Docs: https://example.com/docs" to its text and read it back again to confirm the change
6. Print a final JSON object with fields: profile_id, profile_name, connected_accounts, draft_id, draft_status (as the API reports it when you read the draft back), updated_content

Leave the profile and the draft in place; do not delete them. Do not connect, disconnect or modify any social account, and do not schedule or publish anything.
