v3.3.2 — AI Engine & Bulk AI Generation

Added

• AI Engine Settings Page: New admin page (Search Intel → AI Engine) with provider selection (OpenAI, Anthropic, Ollama), encrypted API key management with save/test buttons, model override, custom endpoint, rate limiting, token budget, and usage statistics
• Bulk AI Content Generation: New section in Bulk Tools for AI-powered generation of all 14 SEO/AEO/GEO fields with grouped checkboxes, Select All toggle, empty-only or overwrite-all modes

Fixed

• Sitemap 404: Register rewrite rules before flush_rewrite_rules() in activation hook so WordPress recognizes /sitemap.xml immediately
• Ollama Rate Limiting: Local models now bypass rate limiting; fixed transient TTL renewal bug that prevented the 60-second window from expiring
