Message:

AI: Prevent wp_supports_ai filter from overriding the WP_AI_SUPPORT constant.

When WP_AI_SUPPORT is explicitly set to false, wp_supports_ai() now returns early before the filter runs. This ensures the site owner's explicit preference to disable AI cannot be overridden by a plugin via the wp_supports_ai filter.

The filter default is now always true, since the constant check happens beforehand.

Developed in: ​https://github.com/WordPress/wordpress-develop/pull/11295

Follow-up to [62067].

Fixes #64706.
