Issue description

Hi there, thanks for maintaining this library,

Using Godot 4.4, and the latest PhantomCamera version 0.8.2.3

Setting a breakpoint near a variable containing a PhantomCamera3D and then trying to inspect the variable triggers nil errors, making it impossible for me to debug with the plugin.
I had to rewrite many getters with a check for camera_3d_resource:

func get_v_offset() -> float:
	if !camera_3d_resource:
		return 0.0
	return camera_3d_resource.v_offset

Steps to reproduce

Create a breakpoint anywhere in a piece of code that contains a PhantomCamera3D variable.
In the debugger, try to inspect the camera object,
an "Invalid access to property or key .... on a base object of type 'Nil'" is thrown

(Optional) Minimal reproduction project
