feat: add directory navigation and env setup for all template examples

- React SDK Demo: add cd examples/react-sdk-demo before npm install, update to VITE_UR_PUBLIC_KEY
- Kanban Board: add cd examples/sdk-kanban before environment setup
- Social Media Clone: add cd examples/social-demo, add env vars (VITE_PUBLIC_KEY, API_KEY) and run instructions
- Python SDK Demo: add cd examples/python-sdk-demo before pip install
- All templates now have consistent sparse checkout + directory navigation flow
