Import Skill to Nexus

Download skill content from Notion and create it locally in 03-skills/.

Purpose

This is an atomic building block that takes skill content (from Notion or other sources) and creates a proper skill folder structure in Nexus. It handles:

• Downloading the skill file from Notion
• Extracting/creating the SKILL.md
• Creating the folder structure
• Auto-backup of existing skills before overwriting
• Batch import of multiple skills at once
• Checking for existing skills (prompt to overwrite)

Typically used after query-notion-db when user selects a skill to import.
