fix(useTimeout): remove window prefix from setTimeout and clearTimeout for platform independence

[dlsxjzld]

Overview

Replace window.setTimeout and window.clearTimeout with the global setTimeout and clearTimeout to align with the project's platform-independent direction introduced in #329

window.setTimeout only works in browser environments, causing issues in SSR (Next.js), React Native, and other non-browser JavaScript environments.

The markdown docs for this hook still mention window.setTimeout (see packages/core/src/hooks/useTimeout/useTimeout.md), which conflicts with the new platform-independent implementation. Please update the docs in the same PR so user-facing documentation stays accurate.

Suggested change

	* It manages `setTimeout` in accordance with the React lifecycle, ensuring cleanup on unmount or when dependencies change.
	* It schedules the callback with a timer in accordance with the React lifecycle, ensuring cleanup on unmount or when dependencies change.

Changeset summary is a bit ungrammatical and reads like it’s missing a noun at the end ("for platform-independent"). Consider rewording to a complete sentence (and typically capitalizing/ending with a period) since this text is user-facing in release notes.

Suggested change

	remove window prefix from setTimeout and clearTimeout for platform-independent
	Remove window prefix from setTimeout and clearTimeout for platform-independent behavior.
