/**
 * TUI-local connection health collection.
 *
 * Mirrors the shape of `@wrongstack/webui-server`'s
 * `collectConnectionsHealth()` but lives here so the TUI does not need a
 * runtime dependency on the WebUI server package. All IPC primitives are
 * available transitively through the TUI's existing dependencies
 * (`@wrongstack/core`, `@wrongstack/kanban`, `@wrongstack/sage`,
 * `@wrongstack/tools`).
