This update improves the CodeEditor component by adding:

1. File Extension Detection

   • Implemented getFileExtension() to retrieve the file extension of the currently open file.

2. Code Commenting/Uncommenting

   • Added addLanguageSymbol(QTextCursor &cursor, const QString commentSymbol)
     • Supports both single-line and multi-line selections.
     • Automatically applies or removes the appropriate comment symbol based on the file type.
   • Implemented addComment(), which:
     • Detects the file extension.
     • Applies the correct comment symbol for C++, Java, Python, YAML, SQL, Bash, JSON, and Go files.

This feature improves the code editor by streamlining the process of toggling comments shortcuts, improving productivity, and ensuring language-specific syntax correctness. 🚀
