fix: Correct zip structure for Claude.ai/Desktop skill uploads (v1.3.0)

Individual skill zips now have SKILL.md at the top level (<skill-name>/SKILL.md)
instead of nested under skills/ directory, fixing uploads to Claude.ai and
Claude Desktop. Also adds missing n8n-code-javascript and n8n-code-python
individual zips. Closes #19
