Generate index-slim.md without metadata for blog.json

- rst2md.py now creates both index.md (with metadata) and index-slim.md (clean)
- generate_jsonblog.py references index-slim.md for clean content
- Fixes "Error: No content found" in blog viewer
- strip_pelican_metadata() removes title and metadata fields
