 * state (header status pill, dashboard health card, …) so they cannot drift.
 *
 * Three queries feed this hook:
 * - {@link useGetPipelineStatusQuery} — provides the run `state`
 *   (`cdc` / `initial-sync` / `not-running`) plus `collectorStates`, the same
 *   value per source (the rolled-up `state` is the least-advanced of those).
 * - {@link useGetPipelineQuery} — provides `config.sources`, the declared
 *   list of source connections (the source of truth for which connections
 *   are expected to exist).
 * - {@link useMonitoringStatisticsQuery} — polls every 5s and provides the
 *   actual reported status per connection. The poll is what makes
 *   `sourceHealth` track live failures.
 *
 * `sourceHealth` is computed only when the collector is active (`cdc` or
 * `initial-sync`); see {@link mapPipelineHealth} for the full decision table.
