feat: Add Currently Reading Book Widget (#57)

[Sneha-0409]

Closes #57

Overview of my PR

This PR introduces the Currently Reading book widget, allowing users to dynamically showcase the books they are actively reading on their GitHub READMEs without relying on manual updates.

Features Added

• Goodreads Integration: Uses the public Goodreads RSS feed (/review/list_rss/) to securely query a user's shelf.
• Zero-Dependency XML Parser: Created a custom fetchText utility and a regex-based XML parser directly within Node.js native http/https. This ensures the project maintains its zero-dependency philosophy!
• Dynamic Cover Loading: The system extracts the book cover image URL, downloads the binary payload, and converts it into a Base64-encoded string natively so it easily embeds inside the SVG.
• Shelf Control: Users can toggle between displaying currently-reading, read, or to-read shelves.
• Frontend Addition: The "Currently Reading" preset was added to index.html allowing visual customization and previews.

UI

Performance & Caching

• Configured via standard cache headers inside api/widget.js.
• Caches for 1 hour (s-maxage=3600, max-age=3600). This is a relatively slow-updating metric, so the 1-hour buffer is highly efficient and guarantees we do not get rate-limited by Goodreads.

Testing Done

• Tested the native Regex logic; successfully parses title, author, and handles CDATA segments dynamically.
• Gracefully handles Edge Cases: If a user has no book currently on their shelf, or if the cover image is missing, the SVG defaults to a cleanly-styled placeholder book outline.
• Tested all visual variables (Theme, Platform, Status) locally using the control panel generator.
