/**
 * Hierarchical query key factory for every Better Auth query managed by
 * this library.
 *
 * Keys are nested — higher-level keys are valid prefixes of their
 * descendants — so a single call can invalidate a whole subtree:
 *
 * ```ts
 * queryClient.invalidateQueries({ queryKey: authQueryKeys.all })
 * queryClient.invalidateQueries({ queryKey: authQueryKeys.user(userId) })
 * queryClient.invalidateQueries({ queryKey: authQueryKeys.session })
 * ```
 *
 * This factory lives in `@better-auth-ui/core` so it can be shared across
 * framework packages (`@better-auth-ui/react`, a future `/solid` package,
 * etc.) and across client- and server-side query variants — the cache
 * entries line up regardless of which query options factory produced them.
 *
 * Plugin-specific query keys live alongside their plugin (e.g.
 * `apiKeyQueryKeys`, `organizationQueryKeys`, `passkeyQueryKeys`,
 * `multiSessionQueryKeys`) and chain off `authQueryKeys.user(userId)` so
 * everything still sits under the shared `["auth", "user", userId, ...]`
 * subtree.
 *
 * For mutation keys, see `authMutationKeys` in `./auth-mutation-keys`.
