Stop button does not immediately stop listing files.

[vi]

1. Download https://github.com/qarmin/czkawka/releases/download/4.1.0/linux_czkawka_gui.AppImage and run in on Debian
2. Add root directory to the included list.
3. Press Search button.
4. It starts listing files - the counter goes up.
5. Press Stop button

Expected:

It hides the progress window immediately and stops disk IO.

Actual:

It keeps counting the files for some time, only then stops and returns to the main window.

Not sure if this is a bug, All remaining atomic tasks(e.g. hashing image) must end correctly. Easier method is to kill process immediately, but this is very discouraged When collecting files to scan I see sometimes lag, because check about exiting from function works rarely, depending on folder structure, so this can be improved

I would say there should be 2 buttons with specific behaviors:

• one that allows to immediately pause searching, returning all the already processed items and discarding those discovered and scheduled for analysis
• one that completely stops discovering items for analysis, waits for them to be analysed and then returns all the processed items So far, the Stop button takes time to finish processing discovered items and does not return anything.
