Issue desciption:
The "Mark file as Viewed" feature marks all files with the same filename, regardless of their folder path, when only one file should be affected.

Steps to Reproduce:

• Find a Pull Request containing files with the same name located in different folders, e.g.:
  • libs/lib-name/src/my-component.component.ts
  • libs/different-lib-name/src/my-component.component.ts
• In the sidebar, locate one of the my-component.component.ts files and click "Mark file as Viewed."
• Observe that all files sharing the same name, regardless of their folder, are now marked as "Viewed."
