/**
 * Creates a Vite plugin that generates TypeScript declaration files with
 * compile-time–safe ID types for all six NQTR entity registries:
 * activities, commitments, locations, maps, quests, and rooms.
 *
 * ---
 *
 * **How it works**
 *
 * At startup (and after every hot-module reload), the plugin executes the
 * content modules listed in the options server-side via Vite SSR.  Those
 * modules register entities by calling `RegisteredActivities.add(...)`,
 * `RegisteredRooms.add(...)`, etc.  The plugin then reads back the IDs from
 * all six registries and writes a `.d.ts` declaration file that augments the
 * `Nqtr*Ids` interfaces in `@drincs/nqtr/registries`.
 *
 * ---
 *
 * **Pixi-VN integration**
 *
 * If `vitePluginPixivn` (from `@drincs/pixi-vn/vite`) is present in the same
 * Vite config, this plugin automatically waits for its `contentLoaded`
 * signal before reading registry state.  This means you can pass a single
 * `content` barrel file to `vitePluginPixivn` and have both plugins read from
 * it without duplicating the option:
 *
 * ```ts
 * // vite.config.ts
 * import { vitePluginPixivn } from "@drincs/pixi-vn/vite";
 * import { vitePluginNqtr } from "@drincs/nqtr/vite";
 *
 * export default defineConfig({
 *   plugins: [
 *     vitePluginPixivn({ content: "./src/content/index.ts" }),
 *     vitePluginNqtr({ typeFilePath: "./src/nqtr.keys.gen.ts" }),
 *   ],
 * });
 * ```
 *
 * The nqtr plugin will piggy-back on pixi-vn's content loading and re-run
 * type generation on every hot-reload triggered by the pixi-vn plugin.
 *
 * ---
 *
 * **Standalone usage** (without pixi-vn)
 *
 * Target specific entity files directly:
 *
 * ```ts
 * vitePluginNqtr({
 *   activities:   "./src/activities/*.ts",
 *   rooms:        "./src/rooms.ts",
 *   locations:    "./src/locations.ts",
 *   maps:         "./src/maps.ts",
 *   typeFilePath: "./src/nqtr.keys.gen.ts",
 * })
 * ```
 *
 * ---
 *
 * **Generated file**
 *
 * The file written to {@link VitePluginNqtrOptions.typeFilePath} looks like:
 *
 * ```ts
 * // nqtr.keys.gen.ts  — auto-generated, do not edit manually
 * export const nqtrActivityIds = ["study", "cook"] as const;
 * export const nqtrRoomIds = ["bedroom", "kitchen"] as const;
 * // …
 *
 * declare module "@drincs/nqtr/registries" {
 *     interface NqtrActivityIds { "study": never; "cook": never; }
 *     interface NqtrRoomIds     { "bedroom": never; "kitchen": never; }
 *     // …
 * }
 * ```
 *
 * The `as const` arrays can be passed to {@link createNqtrHandler} for runtime
 * validation of Ink hashtag commands. The `declare module` augmentation narrows
 * the `*IdType` helpers (`ActivityIdType`, `RoomIdType`, …) from `string` to
 * the union of known literal IDs at compile time.
 *
 * @param options - Optional plugin configuration.
 * @returns A Vite plugin.
