Use WordPress 7.0 core AI client for Plugin Namer

[davidperezgar]

Description

Fixes the fatal error when running Plugin Check on WordPress 7.0 beta 2 by removing the custom AI Connect integration and using WordPress core’s AI client API (wp_ai_client_prompt) for the Plugin Namer tool. The plugin no longer depends on external AI connection code that conflicted with core in WP 7.0 beta 2.

Fixes #1192

Changes

• Use core AI client – Plugin Namer now uses wp_ai_client_prompt() and related core APIs instead of the previous AI Connect trait. AI execution lives in AI_Check_Names::execute_ai_request() with a function_exists('wp_ai_client_prompt') check and a clear message when the AI client is not available (WordPress 7.0+ required).
• Remove Settings page and AI_Connect – Deleted includes/Admin/Settings_Page.php, includes/Traits/AI_Connect.php, and assets/js/admin-settings.js. AI is configured in WordPress 7.0+ core settings only; the plugin no longer provides its own AI settings screen.
• Namer_Page – Added get_ai_config() to validate core AI availability (WP 7.0+, wp_ai_client_prompt, and is_supported_for_text_generation()). Added render_ai_notice() to show a notice on the Namer page when AI connectors are not configured.
• Plugin_Main – Stopped instantiating/registering Settings_Page; only the main Admin page and Namer page are registered.
• AI_Check_Names – Uses core prompt builder only; supports both snake_case and camelCase method names for compatibility with core API. No external AI client dependency.
• readme.txt – Clarified that the Plugin Namer requires WordPress 7.0+ and configured AI connectors in core settings.
• composer.json / composer.lock – Removed any AI Connect–related dependency and kept the rest of the tooling intact.
• phpmd.xml – Adjusted exclusions/comments to match the removal of the Settings page.

Benefits

• Eliminates the fatal error when using Plugin Check with WordPress 7.0 beta 2.
• Aligns the Plugin Namer with WordPress core’s AI features and avoids maintaining a separate AI connection layer.
• Users configure AI once in WordPress 7.0+ settings; no duplicate plugin-specific AI settings.
• Clear messaging when WP < 7.0 or when AI connectors are not set up.

Testing Instructions

1. Check out this branch and ensure the plugin is active in a WordPress 7.0 beta 2 (or newer) environment.
2. Go to Tools → Plugin Check and confirm the main Plugin Check page loads without errors.
3. Go to Tools → Plugin Check Namer and confirm:
   • On WP 7.0+ with AI connectors configured: the form loads and you can run a name check.
   • On WP 7.0+ without AI configured: a notice explains that AI connectors must be configured in WordPress 7.0+ settings; the page still loads without a fatal.
4. On WordPress < 7.0, open Tools → Plugin Check Namer and confirm the page shows the requirement for WordPress 7.0+ and does not fatally error.
5. Run composer lint and composer phpstan (if applicable) and fix any reported issues.

Testing notes

Installed PCP on a WordPress version older than 7.0:

• ✅ The Settings page is not displayed in the menu
• On the Plugin Check Namer page, the Configure AI Connectors button appears.

Upgraded to WordPress 7.0 beta 2:

• On the Plugin Check Namer page, the Plugin Name, Author Name, and AI Model selection fields are shown, even though I haven't configured a connector
• Attempted to add the Anthropic connector, but was unable to save the API Key. I had to disable PCP to be able to add the connector.
• Added the Anthropic connector, reactivated PCPC. On the Plugin Check Namer page, I can't select the Model
• Attempting to check a name, the Ajax request responds with "No models found that support text_generation for this prompt"
• Checking the connectors page, and it appears my Anthropic connector is not connected anymore. Disabling PCP and the connector shows as connected.
