/**
 * Reads the current Better Auth session via the client SDK.
 *
 * This is the Better Auth client SDK (not a same-origin `requestJson` contract),
 * so a plain `useQuery` is correct — there is no boundary contract to bind.
 *
 * `retry: false` preserves the prior fail-fast contract: an auth failure (expired
 * token, startup network partition) surfaces immediately rather than retrying a
 * request that won't succeed.
