Security

• Path filtering — Blocks access to .obsidian/, .git/, node_modules/, and system files
• File type restrictions — Only allows .md, .markdown, and .txt files
• Path traversal prevention — All paths validated to stay within vault boundaries
• Confirmation required — Destructive operations require explicit confirmation
