Recursive path scan

[waveyboym]

Describe your changes

This PR introduces a new feature in the advanced settings that allows users to specify the depth for file scanning. The depth level determines how many directory levels the scanner will traverse before stopping.

Key details:

• Level 1: The scanner only inspects files in the given folder without looking into subfolders.
• Level 2: The scanner inspects the given folder and its immediate subfolders.
• Level 3: The scanner goes one level deeper, inspecting the given folder, its subfolders, and their subfolders.
• The feature uses a breadth-first search approach to traverse the directory tree based on the specified depth.
  Example:
  Suppose the folder structure is as follows:

C:\folder_a
├── file_1.txt
├── folder_aa
│   ├── file_2.txt
│   ├── folder_aaa
│   │   ├── file_3.txt
│   │   └── folder_aaaa
│   └── folder_aab
├── folder_ab

• With Level 1, only C:\folder_a is scanned, returning file_1.txt.
• With Level 2, folder_aa and folder_ab are also scanned, returning file_2.txt and the contents of folder_ab.
• With Level 3, the scanner includes folder_aaa and folder_aab, returning file_3.txt and the files in those subfolders.
• With Level 4 or higher, deeper levels such as folder_aaaa will also be scanned.
