- Implement JSON feed generation in the RssController
- Add new API endpoint to serve JSON feed
- Update RSS feed view to include hidden machine-readable data
This commit introduces a new feature that allows the application to
serve weather art data in JSON format. The JSON feed includes
metadata such as the title, description, and additional custom
fields for better integration with other services. The changes
also enhance the existing RSS feed by embedding machine-readable
data within the HTML structure, improving accessibility and
usability for automated systems.
