v3.3.5 — Fix llms.txt, Reports Meta Keys, Psalm CI

Fixed

• llms.txt served by wrong plugin: Search Intel now deletes static llms.txt files written by other plugins (e.g. AIOSEO) and checks REQUEST_URI directly so our dynamic handler always takes priority
• llms-full.txt 404: Rewrite rules for both llms.txt and llms-full.txt now flushed on activation
• Reports showing zero scores: build_report() was reading from non-existent _search_intel_scores meta key — fixed to use individual _search_intel_seo_score, _search_intel_aeo_score, _search_intel_geo_score, _search_intel_readability_score keys
• Psalm CI failure: Removed stale PossiblyUnusedReturnValue baseline entry for class-core-web-vitals.php
