Rename GitHub Sharing → GitHub Publishing + fix gh CLI detection

Naming:
- Rename section to "🧬 GitHub Publishing" (DNA emoji for dreamweaving)
- Update description: "Publish DreamSongs as static GitHub Pages sites"
- Remove Windows fallback language (WSL works for full system)

gh CLI Detection Fix:
- Add getExtendedEnv() to include common PATH locations
- Obsidian/Electron doesn't inherit full shell PATH
- Now checks /opt/homebrew/bin, /usr/local/bin, ~/.local/bin
