Replace react-router's useSearchParams with TanStack Router's Route.useSearch, which uses structural sharing to return stable references. Components then re-render only when param values actually change instead of on every navigation event.

Shim the Tauri invoke() bridge by checking for __TAURI_INTERNALS__ and proxying calls to a dev server when absent. This lets the same client boot in Chrome where the React DevTools Profiler works fully.

react-router returns fresh URLSearchParams objects every render, cascading re-renders through consumers. TanStack Router provides structural sharing with stable references, eliminating the need for manual useMemo wrappers around parsed params.

Wrap each message in React.memo and render the list with react-virtuoso's VirtuosoMessageList instead of mapping all items. Only visible messages mount in the DOM and only the actively streaming message re-renders.

Once SQLite removes network waits, rendering becomes the bottleneck. Unstable hook references, unvirtualized long lists, and synchronous work like git checkpoints on the critical path become the slowest operations users feel.

Virtualization adds complexity unnecessary for short, static lists under roughly a hundred items. It pays off when rendering hundreds of messages or rows where only a fraction is visible at once.
