Enhancement: Add Duplicate Detection and Confidence Monitoring to StashResults

[KimiinCHN-AGI]

Kenny,
I've been using your "Data Matching for StashResults" script and found it extremely useful. I've added some improvements to help manage scraping results more efficiently, especially in detecting duplicate results and less reliable matches.
Changelog v1.13:

1. Duplicate result detection: Automatically detects when scraping a view returns multiple results (duplicate li elements) and alerts the user.
2. Low confidence warning: It warns if a fingerprint match is in the "red" zone (low confidence), thereby ensuring that no bad matches are missed.
3. Integrated Alert System:

• Problems found: If duplicates or less-reliable matches are found, a crimson alert box appears, with a "Find Problems" button for automatic scrolling to the problem area.
• Data Consistent: If all results are consistent and high-confidence, a teal alert box briefly appears, providing instant visual confirmation.

4. Performance: Added a debounce function to MutationObserver to improve performance during DOM updates.
5. SPA support: Added popstate and refresh-button listeners to make scripts work seamlessly during navigation and re-scraping.
   I've kept the UI consistent with your original color scheme (teal/crimson).
   Hope you find these additional materials useful!
   Best, [Felixman-KM]
