How to detect duplicate shape definitions?

[kubukoz]

Hi!

I would like to detect and prevent duplicate definitions of shapes within a codebase. Does smithy-model allow me to do that?

At the moment, it appears that duplicate definitions are only logged as a warning, and there's nothing in the model loading result that would tell me that this happened. The SourceLocation also gets deduplicated into a single definition.

To reiterate/rephrase, I want to stop people from doing

@length(min: 1)
string NonEmptyString

@length(min: 1)
string NonEmptyString

in my repository. This has happened before (presumably as a result of a mishandled merge conflict) and it's only producing noise.
