chore: update n8n to 2.13.3 and bump version to 2.41.0

Browse Source 
- Updated n8n from 2.12.3 to 2.13.3
- Updated n8n-core from 2.12.0 to 2.13.1
- Updated n8n-workflow from 2.12.0 to 2.13.1
- Updated @n8n/n8n-nodes-langchain from 2.12.0 to 2.13.1
- Rebuilt node database with 1,396 nodes (812 core + 584 community: 516 verified + 68 npm)
- Refreshed community nodes with 581 AI-generated documentation summaries
- Improved documentation generator: strip <think> tags, raw fetch for vLLM chat_template_kwargs
- Incremental community updates: saveNode uses ON CONFLICT DO UPDATE preserving READMEs/AI summaries
- fetch:community now upserts by default (use --rebuild for clean slate)
- Updated README badge and node counts
- Updated CHANGELOG and MEMORY_N8N_UPDATE.md
