Since Class.new is optimized in Ruby 4.0, it is no longer a method call anymore. Instead of getting `c_return` callbacks for `:new`, we get them for `:initialize` when we want to catch the return value for `Class.new` and `Module.new` calls. Moreover, the `return_value` of the tracepoint is correct for `Class.new` but is `nil` for `Module.new` for some reason. Instead dealing with that complexity, it is better to track constants using the relatively new `const_added` hook, as well as the existing TracePoint based mechanisms. Afterall, `const_added` was added partly because we motivated its usage in a tool like Tapioca, so we should have started using it since Ruby 3.3.
The `0.4.14` version doesn't build anymore for me, at least on my local computer, due to a native extension compile error. It seems like we can relax the version pinning and still get the same test behaviour.

I am not sure what the deal is with Ruby 4.0 and Rails 8.0, but it doesn't look related to the changes in this PR. I'll go ahead and merge anyway. |

@amomchilov I believe those were fixed by these lines: https://github.com/Shopify/tapioca/pull/2473/files#diff-b6efeaf7c856fb7aaf37167b260c87ab44d81079038f785fdac34fbf901da5f5R7-R9 |
