docs: add advanced skills for Vitest, Pinia, and Vue built-ins

Add comprehensive reference documentation for:
- Vitest: environments, projects/workspaces, type testing, vi utilities
- Pinia: HMR, Nuxt integration, SSR setup
- Vue: built-in components (Transition, Teleport, Suspense, KeepAlive) and advanced directives

+# useIpcRendererInvoke
+
+Reactive [ipcRenderer.invoke API](https://www.electronjs.org/docs/api/ipc-renderer#ipcrendererinvokechannel-args) result. Make asynchronous operations look synchronous.
+
+## Usage
+
+```ts
+import { useIpcRendererInvoke } from '@vueuse/electron'
+import { computed } from 'vue'
+
+// enable nodeIntegration if you don't provide ipcRenderer explicitly
+// see: https://www.electronjs.org/docs/api/webview-tag#nodeintegration
+// Ref result will return
+const result = useIpcRendererInvoke<string>('custom-channel', 'some data')
+const msg = computed(() => result.value?.msg)
+```
+
+## Type Declarations
+
+```ts
+/**
+ * Returns Promise<any> - Resolves with the response from the main process.
+ *
+ * Send a message to the main process via channel and expect a result ~~asynchronously~~. As composition-api, it makes asynchronous operations look like synchronous.
+ *
+ * You need to provide `ipcRenderer` to this function.
+ *
+ * @see https://www.electronjs.org/docs/api/ipc-renderer#ipcrendererinvokechannel-args
+ * @see https://vueuse.org/useIpcRendererInvoke
+ *
+ * @__NO_SIDE_EFFECTS__
+ */
+export declare function useIpcRendererInvoke<T>(
+  ipcRenderer: IpcRenderer,
