Review Summary
Good work on the core logic for moving and renaming files! However, I'm requesting changes to address a critical error handling issue that causes the application to crash.
In src/app.js, the call to await setDestinationPath(...) is not wrapped in a try...catch block. When an invalid destination is provided (like a directory that doesn't exist), this function throws an error that isn't caught, leading to an unhandled promise rejection that crashes the program. Please ensure all asynchronous operations that can fail are properly handled.
Additionally, the try...catch block within setDestinationPath (around line 20) catches a specific error only to throw a more generic one. It would be more helpful to provide a more descriptive error message that explains why the path is invalid (e.g., 'Destination directory does not exist').

This try...catch block has a logic issue. The throw on line 22 is immediately caught on line 26. This causes a specific error ('Destination is not a directory') to be replaced by a more generic one ('Destination path is invalid'). Consider restructuring this to handle path existence and type checks separately to provide more descriptive error messages.

The setDestinationPath function can throw an error (for example, when a destination directory with a trailing slash doesn't exist). This call is not wrapped in a try...catch block, which will lead to an unhandled promise rejection and cause the program to crash. You should handle potential errors from this function call, just like you do for validateSource and fs.rename.
