[ENHANCEMENT] Update Resource imports when resource files are renamed or moved #600

When a Robot Framework resource file is renamed or moved, existing Resource imports should be updated automatically across the workspace.

If resources/common.resource is renamed to resources/shared.resource or moved to another folder, all affected Resource imports should be adjusted accordingly.

This should work for resource files with both:

• .resource
• .robot (when used as resource files)

Expected behavior

• Renaming a resource file updates all statically resolvable Resource imports that reference it
• Moving a resource file updates all statically resolvable Resource imports that reference it
• The update works across the workspace
