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

+
+Reactive [Vibration API](https://developer.mozilla.org/en-US/docs/Web/API/Vibration_API)
+
+Most modern mobile devices include vibration hardware, which lets software
+code provides physical feedback to the user by causing the device to shake.
+
+The Vibration API offers Web apps the ability to access this hardware,
+if it exists, and does nothing if the device doesn't support it.
+
+## Usage
+
+Vibration is described as a pattern of on-off pulses, which may be of varying
+lengths.
+
+The pattern may consist of either a single integer describing the
+number of milliseconds to vibrate, or an array of integers describing
+a pattern of vibrations and pauses.
+
+```ts
+import { useVibrate } from '@vueuse/core'
+
+// This vibrates the device for 300 ms
+// then pauses for 100 ms before vibrating the device again for another 300 ms:
+const { vibrate, stop, isSupported } = useVibrate({ pattern: [300, 100, 300] })
+
+// Start the vibration, it will automatically stop when the pattern is complete:
+vibrate()
+
+// But if you want to stop it, you can:
+stop()
+```
+
+## Type Declarations
+
+```ts
+export interface UseVibrateOptions
+  extends ConfigurableNavigator, ConfigurableScheduler {
+  /**
+   *
+   * Vibration Pattern
+   *
+   * An array of values describes alternating periods in which the
+   * device is vibrating and not vibrating. Each value in the array
+   * is converted to an integer, then interpreted alternately as
+   * the number of milliseconds the device should vibrate and the
+   * number of milliseconds it should not be vibrating
+   *
+   * @default []
+   *
+   */
+  pattern?: MaybeRefOrGetter<Arrayable<number>>
+  /**
+   * Interval to run a persistent vibration, in ms
+   *
+   * Pass `0` to disable
+   *
+   * @deprecated Please use `scheduler` option instead
+   * @default 0
+   *
+   */
+  interval: number
+}
+export interface UseVibrateReturn extends Supportable {
