Godot crashes when @tool is applied to a script that references a static var dict from another script

[rafalou38]

Tested versions

• Current version: steam / v4.2.2.stable.official [15073af]

System information

Windows 11

Issue description

Godot completely crashes, without error when I apply @tool to my script.
I can still run the project successfully by not loading the tool in the editor or by running from cmdline.

Steps to reproduce

After a lot of testing, I have pinpointed the issue to this:

In the tool script at _ready and _process

unlocked = Economy.research[type]["unlocked"] 

where Economy is

class_name Economy
extends Node2D

static var money := 0.0


static var research := {
    NodeHandler.NodeType.SHOP: {"unlocked": true, "upgrade": 0, "max_buy": 0},
    NodeHandler.NodeType.MINE: {"unlocked": true, "upgrade": 0, "max_buy": 0},
    NodeHandler.NodeType.PROCESSOR: {"unlocked": true, "upgrade": 0, "max_buy": 0},
    NodeHandler.NodeType.REFINERY: {"unlocked": true, "upgrade": 0, "max_buy": 0},
    NodeHandler.NodeType.TETHER: {"unlocked": false, "upgrade": 0, "max_buy": 0},
    NodeHandler.NodeType.DUPLICATOR: {"unlocked": false, "upgrade": 0, "max_buy": 0},
}

Minimal reproduction project (MRP)

I reduced my project to the bare minimum to reproduce this error on the min-bug branch:
https://github.com/rafalou38/IdleGame/tree/min-bug

The tool script is at res://views/shop/shop_item.gd
And the crash can be resolved by comenting the line

@tool
# or
unlocked = Economy.research[type]["unlocked"]

I tested with godot 4.3 stable and instead a crash the editor starts a spam of two errors:

res://views/shop/shop_item.gd:20 - Out of bounds get index '0' (on base: 'Dictionary')
res://views/shop/shop_item.gd:20 - Out of bounds get index '1' (on base: 'Dictionary')

I bisected and the crash was changed to the error spam after #91472. Before this pr the engine crash with this backtrace:
