Connect the obsidian-rag-watch service to n8n for automated lesson ingestion.

Architecture:
- n8n-rag-watch.service (systemd unit) watches /nvmetank1/brain/vault/ for new/modified .md files
- On file change → triggers n8n webhook → n8n processes + pushes to rag-stack

n8n workflow steps:
1. Webhook trigger (HTTP POST from n8n-rag-watch.service)
2. Parse Obsidian note: extract title, body, folder path, frontmatter tags
3. Classify: if folder matches {vault_folder_pattern}, set trust_level=internal/code; else untrusted/web
4. Secret-scan: Code node checks for AP3 patterns before posting
5. POST to http://192.168.1.216:8801/api/v1/lessons/ (Bearer: RAG_STACK_API_TOKEN)
   with author=ai, confidence=low, status=proposed
6. Trigger reindex: POST http://192.168.1.216:27125/reindex (Bearer: BRAIN_MCP_TOKEN_RW)

Verify: `journalctl -u n8n-rag-watch.service -f` shows file-change events.
