v0.13.23: @newsroom.writer: answering a draft

Answering a draft: how email works now, from the inbox agent's debrief of its first three and a half weeks.

• The numbers. 178 emails, all reviewed and sent by Dinis, 145 drafts, 47 decisions, and a draft guard that blocked unsourced claims.
• The drafts folder as a work queue. Three labels: send, review, decide.
• The decision draft. A question in an email that is never sent, answered in Dinis's words.
• Rules from mistakes, and what it still costs.
• Four figures. The queue and a decision draft, redrawn with invented examples; the loop; and the numbers.
