painfully inefficient AI generated python script as extra build step to fix file clangd windows filename issue in vscode

README

DOESNT WORK, FIX ON THE WAY

Steps: 
  
  - create python script
  - add tasks to tasks.json
  - add to all build tasks: "dependsOn": ["fix-compile-commands"]
  
  untested, AI generated, slow and ugly but works for me.
  
  clangd, please fix this and prevent me from making horrible workarounds like these <3
