automation/queen-growth: next best action to earn as a spec of record #5539

The 999-multibots-telegraf Queen needs a spec of record for her per-person "next best action to earn" (slice 1 of the growth mode). The order of seven actions, its thresholds (30-day window, referral from 3 payers, invoices open for 14 days), the caller-only read rule, and three flags that must stay false: sends messages, promises earnings, reads the payments archive.

Spec: specs/automation/queen-growth.t27 (PR #5524). Host: render src/agent/queen-growth.ts, tool hive_growth.
