Summary

Improves WTR-Lab chapter downloading and error handling.

Users have reported downloads getting stuck on Chapter 1 without progressing. WTR-Lab uses a two-step API to retrieve chapters, and downloads can fail when the server returns an incomplete response or requires CAPTCHA verification.

Changes

• Added validation for chapter lists and API responses.
• Added clearer errors for missing chapter content and CAPTCHA verification.
• Added validation for the returned chapter content URL.
• Fixed novel slug parsing when opening WebToEpub from a chapter URL.
• Added regression tests for URL parsing, chapter lists, and invalid API responses.

@chaudhary-lakshay what changes did you make? I think your code does nothing at all. All issues you linked are also marked as completed. I think you used ai and didn't even sanity check the output. The next time you use ai please use the AGENTS.md file.

Added regression tests for URL parsing, chapter lists, and invalid API responses.

Not neccessary

If you want to know more about why the code didn't do what you wrote you can ask here and i will elaborate. Please only do this if you want to learn and not just to waste my time e.g. copy pasting my explanation in ai so it can "correct" the non issues.
