Producers now return structured {producer, severity, text} objects
instead of raw strings. buildReminderChannel collects them, increments
mana_ai_reminders_emitted_total{producer, severity} per emission, and
maps back to strings for the shared-ai loop input.
Why structured: the Prometheus label "severity" lets dashboards split
75-99% token-budget warnings (severity=warn) from 100%+ escalations
(severity=escalate) without NLP on the reminder text. Adding a new
producer that emits only info-level state (e.g. stale-sync warning)
falls out for free.
Active producer labels today:
- token-budget (warn, escalate)
- retry-loop (warn)
With this plus the scrape job (d087b4744), we can finally answer:
"does the budget warning actually change LLM behaviour?" — correlate
reminders_emitted_total{producer='token-budget'} with
tick_duration_seconds or planner_rounds_histogram.
3 tests updated to assert the new {producer, severity, text} shape
(16 reminder tests total, all green).
