[BUG] Deselect not working in "Select by Normal" node

**Describe the bug**
Everything is selected even when the deselect option is enabled
When set to face select mode, the correct face seems to be selected, but operation still use all face/vertex

**To Reproduce**
Steps to reproduce the behavior:

**Expected behavior**
When deselect is enabled, it should remove face from selection

**Desktop (please complete the following information):**
- OS: Windows 10
- Blender Version 2.83
- Sorcar Version 3.2.0

**Additional context**
Add any other context about the problem or your proposed solution here.

Look for the 'Select by Normal' node implementation in the Sorcar addon, likely in a nodes or operators directory. The bug is about the deselect option not working; examine the selection logic and how it interacts with Blender's mesh selection API. Test with a simple mesh to verify the fix removes faces as expected.
