Build a WordPress plugin with AI content generation.

Your plugin needs these files:

• wp-ai-assistant.php for initialization.
• class-api.php for the OpenAI wrapper.
• class-ajax.php for AJAX handlers.
• editor.js for the Gutenberg sidebar.

Follow these steps:

1. Build an API wrapper. Use the API key from your settings page.
2. Create AJAX handlers. These process prompts from the editor.
3. Add a Gutenberg sidebar. Use it to insert AI text as blocks.

Follow these security rules:

• Use check_ajax_referer on every action.
• Use current_user_can to check permissions.
• Sanitize all inputs.
• Escape all outputs.
• Store API keys in wp_options.
