✅ Updated Userscript for Genshin Impact Map — Now Supports markers_all.v4.json

Hi everyone,

I’ve updated my userscript to support the recent filename change on genshin-impact-map.appsample.com, where the marker file is now named markers_all.v4.json.

This version introduces flexible filename matching, allowing the script to work with any marker file that starts with markers_all, regardless of versioning or suffix.

---

🧠 Key Features

• ✅ Flexible filename support
• ✅ Compatible with markers_all.v4.json
• ✅ Future-proof against file renaming
• ✅ Enables marker editing and comments
