/**
 * Returns the current user, linked accounts, auth state, and token helpers.
 *
 * Use `isConnected` for the common "am I connected?" check: true when authenticated and
 * wallet is ready for the current chain.
 *
 * @remarks Client-only. Use in a Client Component (e.g. add `"use client"` in Next.js App Router).
 *
 * @returns user, linkedAccounts, isLoading, isAuthenticated, isConnected, getAccessToken, validateAndRefreshToken
 *
 * @example
 * ```tsx
 * const { user, isConnected, getAccessToken } = useUser()
 *
 * if (!isConnected) return <Spinner />
 * // User is authenticated and wallet is connected — safe to send/sign
 *
 * const token = await getAccessToken()
 * ```
