  repo: introduce git_repository_workdir_path Add a simple accessor for workdir paths to get an absolute on-disk path given a repository and a relative path within it. This is useful to avoid copy-pasta `git_buf_joinpath` and to ensure that we validate working directory paths while honoring `core.longpaths` settings.
