Object.const_defined? not respecting namespace check

[HoneyryderChuck]

👋 reported the same issue for jruby, and can observe the same thing happening when using truffleruby 24.2.1.

Expected Behavior

Given the following snippet, I'd expect the const not to be defined:

Object.const_set :Bang, Module.new
p Object.const_defined?("Bang::Struct") #=>should be false

Actual Behavior

The snippet above returns true, false in cruby. The latter is correct.

Thanks for the report, this most likely happens because it finds top-level ::Struct.
Similarly, p Bang::Struct should be NameError, but currently isn't.
