A task included from the global mise config runs with the config root as its
working directory - $HOME - rather than the directory the user invoked it from.
Deriving the repository from the current directory therefore failed everywhere
except a project-level include, which defeats the point of installing the task
once and using it in every repository.
mise passes the real directory as MISE_ORIGINAL_CWD, so enter it before
resolving the repository, falling back to the current directory when the task
is run directly rather than through mise.
