/**
 * @pellux/goodvibes-sdk/platform/runtime/session-spine
 *
 * The ONE session-spine surface client extracted from the near-twin TUI and agent
 * implementations, plus the cross-surface session read facade (union cache). Both
 * are consumed by two-plus surfaces (TUI, agent, and, in waiting, webui / PWA),
 * which is why they live here per the SDK-boundary rule (machinery needed by 2+
 * surfaces => SDK). See docs/decisions/2026-07-05-session-spine-sdk-extraction.md.
