Create Draft
Create a draft. Supply in_reply_to to create a reply draft (with
reply_all to address the whole thread), whose recipients, subject, and
threading are derived from the referenced message, or forward_of to
create a forward draft, which derives the subject, threading, and
forwarded content from the source but keeps recipients caller-supplied.
**CLI:**
``bash
agentmail inboxes drafts create --inbox-id <inbox_id> --to [email protected] --subject "Draft subject" --text "Draft body"
