The import-skill command doesn't belong in the marketplace — it's a
repo maintenance tool. Move it to .claude/commands/ so it's available
to anyone cloning the repo as /import-skill, no plugin install needed.
- Move command to .claude/commands/import-skill.md
- Move fetch script to scripts/fetch_github_tree.py
- Remove plugin from marketplace.json and README
- Unignore .claude/commands/ in .gitignore
