 * Derives `sourceHealth` from the collector run state and the per-connection
 * statuses reported by the monitoring statistics endpoint.
 *
 * Decision table:
 *
 * | state                      | declared sources | every status `'connected'` | sourceHealth |
 * | -------------------------- | ---------------- | -------------------------- | ------------ |
 * | `cdc` / `initial-sync`     | ≥1               | yes                        | `'healthy'`  |
 * | `cdc` / `initial-sync`     | ≥1               | no / missing / undefined   | `'unhealthy'`|
 * | `cdc` / `initial-sync`     | 0                | n/a                        | `undefined`  |
 * | `not-running` / undefined  | any              | any                        | `undefined`  |
 *
 * Notes:
 * - Status comparison is case-insensitive (`'Connected'` counts as healthy).
 * - A declared source with no entry in `stats.connections` is treated as
 *   unhealthy — its status resolves to `undefined` and fails the check.
 * - When the pipeline isn't running we deliberately return `undefined` so the
 *   UI can hide the health pill instead of showing a misleading verdict.
 *
 * IDEA: this derivation is UI-side today because the SDK only exposes raw
 * connection statuses. If/when the RDI server exposes an aggregated
 * `sourceHealth` field on the status endpoint, drop this util and read it
 * straight from the SDK response.
