+Migrate to Solid.js v2.0 (beta.10)
+
+- Updated peer dependencies to `solid-js@^2.0.0-beta.10` and `@solidjs/web@^2.0.0-beta.10`
+- Changed `isServer` import from `solid-js/web` to `@solidjs/web`
+- Replaced `onMount` with `onSettled`
+- Removed `batch` calls (Solid 2.0 batches automatically via microtasks)
+- Added `INTERNAL_OPTIONS` (`ownedWrite: true`) to signals to prevent owned-scope write warnings
+- Used `noop` from `@solid-primitives/utils` for server-side no-op methods
+- Fixed default events list: removed duplicate `"wheel"` entry (was listed twice as `"wheel"` and `"mousewheel"`)

@@ -65,7 +65,7 @@ The options are:
 - **onPrompt**: `(evt: Event) => void`; when the `idleTimeout` expires, before declaring the idle status, `onPrompt` callback is fired, starting the prompt timer. When invoked, the last event fired before the prompt phase will be passed as a parameter. It defaults to an empty function.
 - **onActive**: `(evt: Event) => void`; callback called when the user resumes activity after having been idle (resuming from prompt phase doesn't trigger `onActive`). The event that triggered the return to activity is passed as a parameter. It defaults to an empty function.
 - **startManually**: `boolean`; requires the event-listeners to be bound manually by using the `start` method, instead of on mount. It defaults to false.
-- **events**: `EventTypeName[]`; a list of the DOM events that will be listened to in order to monitor the user's activity. The events must be of `EventTypeName` type (it can be imported). The list defaults to `['mousemove', 'keydown', 'wheel', 'resize', 'mousewheel', 'mousedown', 'pointerdown', 'touchstart', 'touchmove', 'visibilitychange']`
