feat: git worktree support

Git worktrees don't have a .git directory with a parent, so we need to
look for the git dir via git2's Repository::discover() and then look for
the cache database there. This allows the client to work correctly when
run from a worktree, and also allows the cache database to be shared
between the main repo and its worktrees (since they share the same git
dir and thus the same cache path).
