Feature: Function Node Updates and Comment Processing

[LunaStev]

• Function Node Enhancements:
  • Added new code related to Function nodes, improving their handling and processing in the abstract syntax tree (AST). This brings the AST closer to completion for function-related constructs.
• Comment Block Processing:
  • Refined the processing of comment blocks, ensuring comments are correctly handled and parsed during compilation. This includes the removal of outdated or redundant comment processing code.
• Code Cleanup:
  • Removed unnecessary node files and comments, streamlining the codebase for better readability and maintainability.
• Final Adjustments:
  • Focused on finalizing and cleaning up function-related node processing, eliminating content-free nodes to enhance the AST structure.

This update prepares the Wave language project for further development on function handling and general AST processing.
