Re: [GSoC][PATCH 0/2] Add refs exists subcommand

> This series introduces `git refs exists` as a modern replacement for
> `git show-ref --exists`, continuing the effort to consolidate commands

> The two patches are as follows:
> 
> 1. The first implements the `exists` subcommand. The small amount of
>    logic is duplicated from `show-ref` to avoid unnecessary abstraction.
> 
> 2. The second adds tests by refactoring the `show-ref --exists` tests
>    into a shareable helper, ensuring both commands are tested for
>    identical behavior.
