Implement File and Folder Operations in Context Menu

[chrisdedman]

Description

The Tree::showContextMenu function needs implementations for the following operations:

• Delete a file/folder
  • Unit Test
• Rename a file/folder
  • Unit Test
• Create a new file
  • Unit Test
• Create a new folder
  • Unit Test
• Duplicate file/folder
  • Unit Test

These features should be properly implemented to allow users to manage files and folders via the context menu.

Suggested Implementation

• Hook into the context menu event and provide options for file/folder operations.
• Implement logic to modify the file system accordingly.
• Update the UI to reflect changes after operations are performed.
• Create unit tests to confirm proper implementation of each action.

Relevant Code

CodeAstra/src/Tree.cpp

Line 78 in e93db75

void Tree::showContextMenu(const QPoint &pos)

Additional Notes

The implementation should also handle edge cases such as duplicate names, invalid filenames, and deletion confirmation.
