Feat:Support multi-select to remove multiple directories at once in Settings

### Describe the feature

### Feature
In the **Settings** view, removing directories currently requires clicking the trash icon next to each path individually. When an added path introduces many subdirectories removing them one by one is extremely slow and tedious.

### Solution
Introduce batch-selection controls for the directory list:
- **Checkboxes:** Add a selection checkbox next to each directory entry (or an explicit multi-select mode).
- **Select All / None:** Add a master checkbox or toggle at the top of the list to quickly select all or clear the selection.
- **Batch Action:** Provide a "Remove Selected" (or trash) button in the action bar that deletes all selected paths at once after confirmation.
