/**
 * Svelte store factory that wraps KatanaKit's HTTP GET. Bridges the Safe
 * Result pattern to idiomatic Svelte stores and never throws on HTTP errors.
 *
 * Stale responses are ignored via a request version counter and AbortController;
 * in-flight requests are aborted on component destroy.
 *
 * @param apiName - Name of the registered API (see `useInitApis`).
 * @param endpointName - Name of the endpoint inside that API.
 * @param options - Optional `UrlOptions` (path/query params).
 * @returns Readable stores `{ data, error, loading }` plus `refetch`.
 *
 * @example
 * ```svelte
 * <script lang="ts">
 *   import { useRequest } from "katanakit-js/adapters/svelte";
 *
 *   const { data, error, loading } = useRequest("pokeapi", "pokemonById", { params: { id: 25 } });
 * </script>
 *
 * {#if $loading}
 *   <div>Loading…</div>
 * {:else if $error}
 *   <div>{$error.message}</div>
 * {:else}
 *   <div>{$data?.name}</div>
 * {/if}
