[Bug] Cant open repo.

Description

I have built gitu from source tree. But I cant open any newly cloned repo, even with this gitu repo.

$ gitu
Error: OpenRepo(Error { code: -1, klass: 6, message: "unsupported extension name extensions.refstorage" })

System information

$ rustup --version
rustup 1.28.2 (e4f3ad6f8 2025-04-28)
info: This is the version for the rustup toolchain manager, not the rustc compiler.

Related context

• It's maybe libgit2 error, there have been cases like this
• gitui also suffered from the same issue. See BUG: Error invalid path on valid git repo. · Issue #2700 · gitui-org/gitui
• lazygit who doesnt rely on git2 work just fine.

Start at the gitu startup path that opens a repository and investigate the OpenRepo error on Windows 11 with a newly cloned repository. Reproduce the reported extensions.refstorage failure, then verify that gitu can open both the cloned repository and the gitu repository without the error.
