Bug: `createDebounce()` uses `window.setTimeout` — crashes in SSR environments

[roshinit-a]

Description

createDebounce() in web-components/src/utils/index.ts calls window.setTimeout directly instead of the globally available setTimeout. This causes a ReferenceError: window is not defined crash when the utility is used in a Node.js SSR environment (e.g. SvelteKit, Nuxt, or any server-rendered integration of these web components).

Current Behaviour

// web-components/src/utils/index.ts
export const createDebounce = (debounceTime: number = 500) => {
  let timeout: number | null = null

  return {
    debounce: (callback: () => void) => {
      if (timeout) {
        clearTimeout(timeout)
      }
      timeout = window.setTimeout(() => {  // ❌ window is not available in SSR
        callback()
        timeout = null
      }, debounceTime)
    },
    ...
  }
}

In Node.js, window is undefined, so any module that imports and calls createDebounce() during SSR will throw:

ReferenceError: window is not defined

Expected Behaviour

The function should use the environment-agnostic setTimeout (without the window. prefix), which works in both browser and Node.js:

- timeout = window.setTimeout(() => {
+ timeout = setTimeout(() => {

setTimeout is part of the global scope in both browser and Node.js environments, so this is a safe, zero-impact change.

Context

This follows the same SSR compatibility pattern as issue #469 / PR #470, where window.matchMedia in dark-mode-listener.ts was guarded for SSR. The createDebounce utility has the same problem but with a simpler fix — no guard needed, just drop the window. prefix.

Proposed Fix

// web-components/src/utils/index.ts

export const createDebounce = (debounceTime: number = 500) => {
  let timeout: number | null = null

  return {
    debounce: (callback: () => void) => {
      if (timeout) {
        clearTimeout(timeout)
      }
-     timeout = window.setTimeout(() => {
+     timeout = setTimeout(() => {
        callback()
        timeout = null
      }, debounceTime)
    },
    clear: () => {
      if (timeout) {
        clearTimeout(timeout)
        timeout = null
      }
    },
  }
}

Happy to open a PR for this if it looks good!
