fix: Correct Ollama model name + strict blank-line heading detection

1. LLM model: qwen3:32b → qwen3.5:35b-a3b (actual model on Mac Mini)
2. Section splitter: headings MUST be preceded by a blank line.
   This prevents cookie table entries ("Funktionale Cookies",
   "Session Cookies") from splitting the cookie section.
