Deserialization aliases objects with the same shape

[SilverEzhik]

> local data = hs.json.decode('{"props":{},"children":{}}');  
> print(data.props == data.children)
true

> local data = hs.json.decode('{"props":{"a": 1},"children":{"a": 1}}');  
> print(data.props == data.children)
true

This seems really weird - this means that any two objects with an identical shape will be aliased to one another, causing weird and unpredictable behavior. I've noticed that so far this affects both hs.json and hs.settings.

As a workaround, I've been using https://github.com/rxi/json.lua instead - it can be assigned to hs.json and provides the same interface.

I'm using Hammerspoon 1.0.0 and macOS Tahoe 26.0.1 (25A362).
