/**
 * `maybeRefreshAggregate` — Q4=A on-demand aggregate refresh. Recomputes
 * `phase-complete` / `epic-complete` events only when the current webhook
 * payload could plausibly change an aggregate state (completed:* label,
 * issue.closed, pull_request.closed). Zero GraphQL cost on non-completion
 * payloads.
 *
 * Contract: `specs/978-summary-generacy-cockpit/contracts/aggregate-on-demand.md`.
