/**
 * Re-sync the active conversation with the backend whenever the chat window is opened.
 *
 * The host shell hosts several micro-frontends (Catalog, Metric editor, Analytical Designer) and
 * keeps their runtimes alive across client-side navigation. Each runtime owns its own GenAI redux
 * store, which is only populated once on initial mount. As a result, a conversation started or
 * switched to on one micro-frontend was not reflected on another until a full page reload.
 *
 * When the chat is (re)opened we re-fetch the conversation list from the backend and, if another
 * conversation has become the most recently active one, switch to it. We then re-fetch the active
 * thread from the backend and replace the cached messages atomically so that messages created on
 * another micro-frontend show up even when this runtime already had the conversation cached. This
 * keeps the conversation and its messages in sync across host navigation without requiring a manual
 * reload. A flaky/empty backend response never clears what the user is currently looking at.
 *
 * Only runs in agentic conversations mode and only after the initial load finished. A brand-new
 * unsent draft conversation or an in-progress message exchange is never replaced.
