PHP 8 warning — undefined variable $atomchat_asset_version (v1.1.8)

Plugin: AtomChat 1.1.8
PHP: 8.4
File: includes/atomchat_cloud.php, lines 22, 40, 41

Error:
PHP Warning: Undefined variable $atomchat_asset_version in
…/wp-content/plugins/atomchat/includes/atomchat_cloud.php on line 22

Cause:
The function declares global $atomchat_base; but also uses
$atomchat_asset_version, which is defined at file scope in installer.php
and never declared global. Under PHP 8+ this throws a warning on every
request, and wp_enqueue_script() receives null as the version argument,
which breaks asset cache-busting after plugin updates.

Suggested fix:
global $atomchat_base, $atomchat_asset_version;

I’ve applied this patch locally and it resolves the warnings.
